Subject: [PATCH 5.10.y 3/4] i2c: qcom-cci: Do not check return value of cci_init()
Date: Thu, 10 Sep 2026 20:15:28 -0400	[thread overview]
Message-ID: <20260911001529.3302151-3-sashal@kernel.org> (raw)
In-Reply-To: <20260911001529.3302151-1-sashal@kernel.org>

[ Upstream commit 17c5d247e3e4708cac05ff087c8013c0dda383a2 ]

The cci_init() function is not supposed to fail, and it never returns
a non-zero, so it'd make sense to convert its signature to void.

Stable dependency adaptation for 5.10:

Resolve the probe conflict against the earlier dependency's IRQ cleanup,
which renamed the failure destination from error to disable_clocks.
cci_init() only writes registers and always returned zero in this tree,
so retain the void conversion and replace its checked probe call with
an unconditional call. Keep the real cci_reset() failure path unchanged.

Retain the separate cci_init() calls in probe, queue timeout recovery,
and runtime resume because this branch does not have the later upstream
refactor moving initialization into cci_reset(). No functions are added.
The target f98d49864821 applies cleanly with Git's three-way merge;
its runtime PM cleanup changes remain in the target.
