Subject: ACPI: GTDT: Get rid of acpi_arch_timer_mem_init()
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=155f8d4ef0b78afbf25b1449bbd654fd1327cc7a;p=thirdparty%2Fkernel%2Flinux.git

ACPI: GTDT: Get rid of acpi_arch_timer_mem_init()

Since 0f67b56d84b4c ("clocksource/drivers/arm_arch_timer_mmio: Switch
over to standalone driver"), acpi_arch_timer_mem_init() is unused.

Remove it.
