Subject: [PATCH v2 6/6] mmc: sdhci-pci: Remove dead code (rst_n_gpio et al)
Date: Wed, 13 Oct 2021 23:17:23 +0300	[thread overview]
Message-ID: <20211013201723.52212-7-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20211013201723.52212-1-andriy.shevchenko@linux.intel.com>

There is no user of this member. Remove the dead code for good.

The removal is dependent on previous removal of cd_gpio, cd_irq.
