Subject: [PATCH] DS1302: local_irq_disable() is redundant after local_irq_save()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=efc47135e4b6f7e7d81332f50ef68e4a42819d20;p=linux-beck.git

[PATCH] DS1302: local_irq_disable() is redundant after local_irq_save()

drivers/char/ds1302.c::get_rtc_time() contains local_irq_disable() call
after local_irq_save(). This looks redundant.

drivers/char/ds1302.c::rtc_ioctl() contains local_irq_disable() call after
local_irq_save(). This looks redundant.
