Subject: [PATCH] staging: mt7621-pinctrl: fix uninitialized variable ngroups
Date: Sat, 10 Nov 2018 23:28:06 +0000 [thread overview]
Message-ID: <20181110232806.14255-1-colin.king@canonical.com> (raw)
From: Colin Ian King <colin.king@canonical.com>
Currently the for_each_node_with_property loop us incrementing variable
ngroups however it was not initialized and hence will contain garbage.
Fix this by initializing ngroups to zero.
Detected with static analysis with cppcheck:
drivers/staging/mt7621-pinctrl/pinctrl-rt2880.c:89]: (error) Uninitialized
variable: ngroups
Fixes: e12a1a6e087b ("staging: mt7621-pinctrl: refactor rt2880_pinctrl_dt_node_to_map function")
