[PATCH 6.6.y 2/3] i2c: omap: Fix an error handling path in omap_i2c_probe()

[Sasha Levin <sashal@kernel.org>]

From: Christophe JAILLET <christophe.jaillet@wanadoo.fr>

[ Upstream commit 666c23af755dccca8c25b5d5200ca28153c69a05 ]

If an error occurs after calling mux_state_select(), mux_state_deselect()
should be called as already done in the remove function.

Fixes: b6ef830c60b6 ("i2c: omap: Add support for setting mux")
