pinctrl: mediatek: Initialize variable pullen and pullup to zero
[ Upstream commit a298c70a10c604a6b3df5a0aa56597b705ba0f6b ]
Coverity spotted that pullen and pullup is not initialized to zero in
mtk_pctrl_show_one_pin. The uninitialized variable pullen is used in
assignment statement "rsel = pullen;" in mtk_pctrl_show_one_pin, and
Uninitialized variable pullup is used when calling scnprintf. Fix this
coverity by initializing pullen and pullup as zero.
Fixes: 184d8e13f9b1 ("pinctrl: mediatek: Add support for pin configuration dump via debugfs.")
