From 7bfd82bff60ef572b9acef8ca32669ace1f50664 Mon Sep 17 00:00:00 2001 From: "Gustavo A. R. Silva" Date: Fri, 5 Oct 2018 20:56:23 +0200 Subject: ath10k: remove unnecessary comparison of unsigned integer with < 0 There is no need to compare *ps_state_enable* with < 0 because such variable is of type u8 (8 bits, unsigned), making it impossible to hold a negative value. Fix this by removing such comparison. Addresses-Coverity-ID: 1473921 ("Unsigned compared against 0") Signed-off-by: Gustavo A. R.
