[PATCH] staging: rtl8723bs: remove redundant comparisons of unsigned ints with >= 0

Show all headers | View raw

From: Colin Ian King <colin.king@canonical.com>

The comparison of mode >= 0 is redundant as mode is a u32 and this
is always true.  Remove this redundant code.

Detected with CoverityScan ("Unsigned compared against 0")
