[PATCH 2/2] pinctrl: mediatek: Initialize variable *buf to zero
From: Guodong Liu <hidden>
Date: 2023-01-18 06:46:35
Also in:
linux-gpio, linux-mediatek, lkml
Subsystem:
pin control subsystem, pin controller - mediatek, the rest · Maintainers:
Linus Walleij, Sean Wang, Linus Torvalds
Coverity spotted that *buf is not initialized to zero in
mtk_pctrl_dbg_show. Using uninitialized variable *buf as argument to %s
when calling seq_printf. Fix this coverity by initializing *buf as zero.
Fixes: 184d8e13f9b1 ("pinctrl: mediatek: Add support for pin configuration
dump via debugfs.")
