Subject: clocksource/drivers/h8300_timer8: Fix irq return value check
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=54a0cd5a7e107ba0cf15a4fb876595d0c8a7faab;p=linux-beck.git

clocksource/drivers/h8300_timer8: Fix irq return value check

The value returned in case of error for the 'irq_of_parse_and_map' function is
zero in case of error. Fix the check in the init code.
