Subject: [PATCH 04/10] pinctrl: mediatek: mt7981: Add missing entries to mt7981_ant_sel_funcs
Date: Tue,  3 Nov 2026 21:29:09 +0000	[thread overview]
Message-ID: <20261103213002.1673560-5-lee@kernel.org> (raw)
In-Reply-To: <20261103213002.1673560-1-lee@kernel.org>

mt7981_ant_sel_pins[] defines 14 pins (pins 14..25, 34, and 35), all of
which select ANT_SEL at function mux mode 6, but mt7981_ant_sel_funcs[]
only contains 12 entries.  When mtk_pinmux_set_mux() iterates over
grp->num_pins (14), it reads two int elements past the end of
mt7981_ant_sel_funcs[].

Add the two missing mode 6 entries to mt7981_ant_sel_funcs[] so its
length matches mt7981_ant_sel_pins[].

Fixes: 6c83b2d94fcc ("pinctrl: add mt7981 pinctrl driver")
Closes: https://sashiko.dev/#/bug/linux-6233f285-1487-4d2d-afe3-d4ce3c445054
