Subject: mtd: rawnand: mpc5121: Replace NO_IRQ by 0
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=3fea699cb2d6c8c47289b16500590630f507d8fd;p=linux.git

mtd: rawnand: mpc5121: Replace NO_IRQ by 0

NO_IRQ is used to check the return of irq_of_parse_and_map().

On some architecture NO_IRQ is 0, on other architectures it is -1.

irq_of_parse_and_map() returns 0 on error, independent of NO_IRQ.

So use 0 instead of using NO_IRQ.
