Subject: [media] exynos4-is: fix error handling of irq_of_parse_and_map
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=9a7a848df1995f05f750b4ed491ac80a459c912f;p=linux-beck.git

[media] exynos4-is: fix error handling of irq_of_parse_and_map

Return value of irq_of_parse_and_map() is unsigned int, with 0
indicating failure, so testing for negative result never works.
