X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=928635c114adefc58aeb1a9f9615cd9d3c24e3e4;p=linux.git

mmc: s3cmci: Fix platform_get_irq's error checking

The platform_get_irq() function returns negative if an error occurs.
zero or positive number on success. platform_get_irq() error checking
for zero is not correct.
