Subject: [PATCH] staging: rtl8192e: Use min_t/max_t macros for variable comparison
Date: Thu, 3 Nov 2022 04:06:59 +0530	[thread overview]
Message-ID: <Y2LxC2kziM1TznhO@qemulion> (raw)

Simplify code by using min_t and max_t 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.

Use the *_t variants of min/max macros to avoid compiler warnings about
data typecast.
Also, use u32 as type for min_t macro to avoid any truncation of data
associated with enum constant HT_AGG_SIZE_32K.
