Subject: [PATCH v2 2/5] rtc: rtc-cmos: Call rtc_wake_setup() from cmos_do_probe()
Date: Wed, 09 Nov 2022 13:09:07 +0100 [thread overview]
Message-ID: <2143522.irdbgypaU6@kreacher> (raw)
In-Reply-To: <5640233.DvuYhMxLoT@kreacher>
From: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
To reduce code duplication, move the invocation of rtc_wake_setup()
into cmos_do_probe() and simplify the callers of the latter.
No intentional functional impact.
