Subject: [PATCH v1 1/2] mmc: slot-gpio: Refactor mmc_gpio_alloc()
Date: Wed, 29 Sep 2021 14:17:56 +0300	[thread overview]
Message-ID: <20210929111757.52625-1-andriy.shevchenko@linux.intel.com> (raw)

Refactor mmc_gpio_alloc() to drop unneeded indentation level
and double condition. This increases readability of the code.
