Subject: [PATCH v1 2/3] pwm: core: Get rid of unused devm_of_pwm_get()
Date: Sat,  6 Aug 2022 18:25:16 +0300	[thread overview]
Message-ID: <20220806152517.78159-2-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20220806152517.78159-1-andriy.shevchenko@linux.intel.com>

The devm_of_pwm_get() has recently lost its single user, drop
the dead API as well.

Note, the new code should use either plain pwm_get() or managed
devm_pwm_get() or devm_fwnode_pwm_get() APIs.
