Next: [PATCH V3 2/5] mmc_block: Add discard support
From: Wan ZongShun on 24 Jun 2010 04:50 This patch is to make returning time checking function valid. In spite of using the 'rtc_valid_tm', nevertheless, the read time function omits its returning value, that means the 'rtc_valid_tm' is useless here.
