Subject: [PATCH v2 14/22] i2c: ocores: Remove #ifdef guards for PM related functions
Date:   Sat, 22 Jul 2023 13:50:38 +0200
Message-Id: <20230722115046.27323-15-paul@crapouillou.net>
In-Reply-To: <20230722115046.27323-1-paul@crapouillou.net>

Use the new PM macros for the suspend and resume functions to be
automatically dropped by the compiler when CONFIG_PM or
CONFIG_PM_SLEEP are disabled, without having to use #ifdef guards.

This has the advantage of always compiling these functions in,
independently of any Kconfig option. Thanks to that, bugs and other
regressions are subsequently easier to catch.
