Takashi Iwai 25aa8e9f10 ALSA: ctxfi: Fix out-of-range access
commit 76c4718322 upstream.

The master and next_conj of rcs_ops are used for iterating the
resource list entries, and currently those are supposed to return the
current value.  The problem is that next_conf may go over the last
entry before the loop abort condition is evaluated, and it may return
the "current" value that is beyond the array size.  It was caught
recently as a GPF, for example.

Those return values are, however, never actually evaluated, hence
basically we don't have to consider the current value as the return at
all.  By dropping those return values, the potential out-of-range
access above is also fixed automatically.

This patch changes the return type of master and next_conj callbacks
to void and drop the superfluous code accordingly.

Aditya Srivastava a08b9f2f22 ALSA: ctxfi: fix comment syntax in file headers
The opening comment mark '/**' is used for highlighting the beginning of
kernel-doc comments.
There are files in sound/pci/ctxfi which follow this syntax in their file
headers, i.e. start with '/**' like comments, which causes unexpected
warnings from kernel-doc.

E.g., running scripts/kernel-doc -none on sound/pci/ctxfi/ctresource.c
causes this warning:
"warning: wrong kernel-doc identifier on line:
 * Copyright (C) 2008, Creative Technology Ltd. All Rights Reserved."

Similarly for other files too.

Provide a simple fix by replacing the kernel-doc like comment syntax with
general format, i.e. "/*", to prevent kernel-doc from parsing it.

Apply const prefix to each possible place: the DAIO tables and the
register offset table.

Just for minor optimization and no functional changes.

Sudip Mukherjee 0cae90a96c ALSA: ctxfi: pr_* replaced with dev_*
pr_* macros replaced with dev_* as they are more preffered over pr_*.
each file which had pr_* was reviewed manually and replaced with dev_*.
here we have actually used the various snd_card which was added to some
structures of ctxfi via a previous patch of this series.

in the ctvmem.c file we have passed a reference of ct_atc as an
argument to get_vm_block function so that it can be used from
dev_*.

since dev_* will print the device information , so the prefix of
"ctxfi" from the various pr_* were also removed.

Sudip Mukherjee 66640898ed ALSA: ctxfi: changed void * to struct hw *
in the code we have void *hw and while using we are always typecasting
it to (struct hw *). it is better to use void type of pointer when we
store different types of pointer , but in this code we are only having
struct hw.
So changed all the relevant reference of void *hw to struct hw *hw,
without any modification of the existing code logic.
the next patch of the series will remove the typecasting which is
not required now.
