[PATCH 08/11] mtd: nand: denali: return error code from devm_request_irq() on error

From: Masahiro Yamada
Date: Tue Nov 08 2016 - 23:35:30 EST


The devm_request_irq() returns an appropriate error value when it
fails. Use it instead of the fixed -ENODEV.

While we are here, reword the comment to make it fit in a single
line, fixing the misspelling of "initialization".
