Subject: Input: palmas-pwrbutton - handle return value of platform_get_irq()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=daf87bffd02e35387a62c77eb32337c934cf631a;p=linux.git

Input: palmas-pwrbutton - handle return value of platform_get_irq()

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