Subject: [PATCH] rtc: pcf8523: rename REG_OFFSET register
Date: Sun,  6 Jun 2021 09:24:23 -0700	[thread overview]
Message-ID: <20210606162423.22235-1-rdunlap@infradead.org> (raw)

REG_OFFSET is defined both here and in arch/arm/mach-ixp4xx/, which
causes a build warning, so rename this macro in the RTC driver.

../drivers/rtc/rtc-pcf8523.c:44: warning: "REG_OFFSET" redefined
   44 | #define REG_OFFSET   0x0e

../arch/arm/mach-ixp4xx/include/mach/platform.h:25: note: this is the location of the previous definition
   25 | #define REG_OFFSET 3

Fixes: bc3bee025272 ("rtc: pcf8523: add support for trimming the RTC oscillator")
