Subject: [PATCH 6/6 v2] mmc: sunxi-mmc: Handle return value of platform_get_irq
Date: Sat, 18 Nov 2017 15:03:48 +0530	[thread overview]
Message-ID: <27a6d3a22516b3711b48bfbf305b6d8f3960eeac.1510997223.git.arvind.yadav.cs@gmail.com> (raw)

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

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