Subject: [PATCH AUTOSEL 5.15 1/3] i2c: Fix conditional for substituting empty ACPI functions

From: Richard Fitzgerald <rf@...nsource.cirrus.com>

[ Upstream commit f17c06c6608ad4ecd2ccf321753fb511812d821b ]

Add IS_ENABLED(CONFIG_I2C) to the conditional around a bunch of ACPI
functions.

The conditional around these functions depended only on CONFIG_ACPI.
But the functions are implemented in I2C core, so are only present if
CONFIG_I2C is enabled.
