Subject: [PATCH] staging: rtl8723bs: Use min/max macros for variable comparison
Date: Thu, 3 Nov 2022 12:32:09 +0530	[thread overview]
Message-ID: <Y2NncTaRJhLvJ4fV@qemulion> (raw)

Simplify code by using min and max helper macros in place of lengthy
if/else block oriented logical evaluation and value assignment. This
issue is identified by coccicheck using the minmax.cocci file.

Signed-off-by: Deepak R Varma <drv@mailo.com>

Please note:
   1. Using min for max_AMPDU_len computation warning was NOT auto generated by
      the cocciecheck command. This was caught while surround code review and
      was manually changed.
   2. Checkpatch script continues to complaint about min_MPDU_spacing
      computation line being more than 100 character in length. I did not find a
      better formatting that will address this checkpatch warning. Any
      suggestions are most welcome.
   3. Proposed changes are compile tested only on my x86 based VM.
