Randy Dunlap 8a171c5cc9 atm: nicstar: fix if-statement empty body warning
When debugging via PRINTK() is not enabled, make the PRINTK()
macro be an empty do-while block.

Thix fixes a gcc warning when -Wextra is set:
../drivers/atm/nicstar.c:1819:23: warning: suggest braces around empty body in an ‘else’ statement [-Wempty-body]

I have verified that there is no object code change (with gcc 7.5.0).

Wenwen Wang fa865ba183 firestream: fix memory leaks
In fs_open(), 'vcc' is allocated through kmalloc() and assigned to
'atm_vcc->dev_data.' In the following execution, if an error occurs, e.g.,
there is no more free channel, an error code EBUSY or ENOMEM will be
returned. However, 'vcc' is not deallocated, leading to memory leaks. Note
that, in normal cases where fs_open() returns 0, 'vcc' will be deallocated
in fs_close(). But, if fs_open() fails, there is no guarantee that
fs_close() will be invoked.

To fix this issue, deallocate 'vcc' before the error code is returned.

Gustavo A. R. Silva ea443e5e98 atm: iphase: Fix Spectre v1 vulnerability
board is controlled by user-space, hence leading to a potential
exploitation of the Spectre variant 1 vulnerability.

This issue was detected with the help of Smatch:

drivers/atm/iphase.c:2765 ia_ioctl() warn: potential spectre issue 'ia_dev' [r] (local cap)
drivers/atm/iphase.c:2774 ia_ioctl() warn: possible spectre second half.  'iadev'

drivers/atm/iphase.c:2816 ia_ioctl() warn: possible spectre second half.  'iadev'
drivers/atm/iphase.c:2823 ia_ioctl() warn: possible spectre second half.  'iadev'
drivers/atm/iphase.c:2830 ia_ioctl() warn: potential spectre issue '_ia_dev' [r] (local cap)
drivers/atm/iphase.c:2845 ia_ioctl() warn: possible spectre second half.  'iadev'
drivers/atm/iphase.c:2856 ia_ioctl() warn: possible spectre second half.  'iadev'

Fix this by sanitizing board before using it to index ia_dev and _ia_dev

Notice that given that speculation windows are large, the policy is
to kill the speculation on the first load and not worry if it can be
completed with a dependent load/store [1].

Linus Torvalds 2c1212de6f SPDX update for 5.2-rc2, round 1
Here are series of patches that add SPDX tags to different kernel files,
 based on two different things:
   - SPDX entries are added to a bunch of files that we missed a year ago
     that do not have any license information at all.
 
     These were either missed because the tool saw the MODULE_LICENSE()
     tag, or some EXPORT_SYMBOL tags, and got confused and thought the
     file had a real license, or the files have been added since the last
     big sweep, or they were Makefile/Kconfig files, which we didn't
     touch last time.
 
   - Add GPL-2.0-only or GPL-2.0-or-later tags to files where our scan
     tools can determine the license text in the file itself.  Where this
     happens, the license text is removed, in order to cut down on the
     700+ different ways we have in the kernel today, in a quest to get
     rid of all of these.
 
 These patches have been out for review on the linux-spdx@vger mailing
 list, and while they were created by automatic tools, they were
 hand-verified by a bunch of different people, all whom names are on the
 patches are reviewers.
 
 The reason for these "large" patches is if we were to continue to
 progress at the current rate of change in the kernel, adding license
 tags to individual files in different subsystems, we would be finished
 in about 10 years at the earliest.
 
 There will be more series of these types of patches coming over the next
 few weeks as the tools and reviewers crunch through the more "odd"
 variants of how to say "GPLv2" that developers have come up with over
 the years, combined with other fun oddities (GPL + a BSD disclaimer?)
 that are being unearthed, with the goal for the whole kernel to be
 cleaned up.
 
 These diffstats are not small, 3840 files are touched, over 10k lines
 removed in just 24 patches.

Colin Ian King cb12d72b27 atm: he: fix sign-extension overflow on large shift
Shifting the 1 by exp by an int can lead to sign-extension overlow when
exp is 31 since 1 is an signed int and sign-extending this result to an
unsigned long long will set the upper 32 bits.  Fix this by shifting an
unsigned long.

Detected by cppcheck:
(warning) Shifting signed 32-bit value by 31 bits is undefined behaviour

We already need to zero out memory for dma_alloc_coherent(), as such
using dma_zalloc_coherent() is superflous. Phase it out.

Nathan Chancellor 64b9d16e2d atm: zatm: Fix empty body Clang warnings
Clang warns:

        zwait;
             ^
drivers/atm/zatm.c:513:7: note: put the semicolon on a separate line to

Get rid of this warning by using an empty do-while loop. While we're at
it, add parentheses to make it clear that this is a function-like macro.

In this case, that loop is expected to be empty so silence the warning
