Subject: [PATCH][next] soundwire: qcom: Fix a u8 comparison with less than zero
Date: Wed, 31 Mar 2021 15:09:44 +0100 [thread overview]
Message-ID: <20210331140944.1421940-1-colin.king@canonical.com> (raw)
From: Colin Ian King <colin.king@canonical.com>
Variable devnum is being checked for a less than zero error return
however the comparison will always be false because devnum is an 8 bit
unsigned integer. Fix this by making devnum an int. Also there is no
need to iniitialize devnum with zero as this value is no read, so
remove the redundant assignment.
Addresses-Coverity: ("Unsigned compared against 0")
Fixes: c7d49c76d1d5 ("soundwire: qcom: add support to new interrupts")
