Subject: [PATCH-next 16/20] gpio: gpio-omap: clean up omap_gpio_restore_context()
Date: Mon, 10 Jun 2019 20:10:59 +0300 [thread overview]
Message-ID: <20190610171103.30903-17-grygorii.strashko@ti.com> (raw)
In-Reply-To: <20190610171103.30903-1-grygorii.strashko@ti.com>
From: Russell King <rmk+kernel@armlinux.org.uk>
Use local variables to store the base iomem address and regs table
pointer like omap_gpio_init_context() does. Not only does this make
the function neater, it also avoids unnecessary reloads of the same
data multiple times.
