Linus Torvalds af995383eb SCSI misc on 20201023
The set of core changes here is Christoph's submission path cleanups.
 These introduced a couple of regressions when first proposed so they
 got held over from the initial merge window pull request to give more
 testing time, which they've now had and Syzbot has confirmed the
 regression it detected is fixed.  The other main changes are two
 driver updates (arcmsr, pm80xx) and assorted minor clean ups.

of the ->bios_param instances calling this function, and use true/false

Mauro Carvalho Chehab dade67f4a5 scsi: docs: convert arcmsr_spec.txt to ReST
This file had its own peculiar style, not following any other
files inside the Kernel (as far as I saw).

Had to do a number of changes here, starting by removing the two
leading asterisks from each line, adding table and literal
block markups and changing whitespace and blank lines.

The end result is that (IMHO), it is now a lot easier to read
it as a text file, while producing a good html output.

Arnd Bergmann 45596c7889 scsi: arcmsr: avoid do_gettimeofday
The arcmsr uses its own implementation of time_to_tm(), along with
do_gettimeofday() to read the current time. While the algorithm used
here is fine in principle, it suffers from two problems:

- it assigns the seconds portion of the timeval to a 32-bit unsigned
  integer that overflows in 2106 even on 64-bit architectures.

- do_gettimeofday() returns a time_t that overflows in 2038 on all
  32-bit systems.

This changes the time retrieval function to ktime_get_real_seconds(),
which returns a proper 64-bit value, and replaces the open-coded
time_to_tm() algorithm with a call to the safe time64_to_tm().

I checked way all numbers are indexed and found that months are given in
range 0..11 while the days are in range 1..31, same as 'struct tm', but
the year value that the firmware expects starts in 2000 while 'struct
tm' is based on year 1900, so it needs a small adjustment.

[mkp: checkpatch tweaks]

Colin Ian King 3c62ecda0e scsi: arcmsr: remove redundant check for secs < 0
The check for secs being less than zero is redundant for two reasons.
Firstly, secs is unsigned so the check is always going to be false.
Secondly, if secs was signed the proceeding calculation of secs is never
going to be negative.  Hence we can remove this redundant check and day
and secs re-adjustment.

Detected by static analysis with smatch:
arcmsr_set_iop_datetime() warn: unsigned 'secs' is never less than zero.
