Subject: [PATCH][next] iwlwifi: mvm: fix comparison of u32 variable with less than zero
Date: Mon, 1 Jul 2019 17:26:57 +0100 [thread overview]
Message-ID: <20190701162657.15174-1-colin.king@canonical.com> (raw)
From: Colin Ian King <colin.king@canonical.com>
The comparison of the u32 variable wgds_tbl_idx with less than zero is
always going to be false because it is unsigned. Fix this by making
wgds_tbl_idx a plain signed int.
Addresses-Coverity: ("Unsigned compared against 0")
Fixes: 4fd445a2c855 ("iwlwifi: mvm: Add log information about SAR status")
Signed-off-by: Colin Ian King <colin.king@canonical.com>
