[PATCH 5/6 v2] mmc: sh_mmcif: Handle return value of platform_get_irq

From: Arvind Yadav <hidden>
Date: 2017-11-18 09:36:28
Also in: linux-amlogic, linux-mmc, lkml
Subsystem: multimedia card (mmc), secure digital (sd) and sdio subsystem, the rest · Maintainers: Ulf Hansson, Linus Torvalds

platform_get_irq() can fail here and we must check its return value.

Signed-off-by: Arvind Yadav <redacted>

changes in v2 :
              Add failure case '<= 0' instead of '< 0'. IRQ0 is not valid.
