[PATCH 3/6 v2] mmc: sdhci-acpi: Handle return value of platform_get_irq

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
