X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a1a3c2d551792747f85857a0c18609650d5948d8;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

gpio: davinci: use devm_irq_alloc_descs()

This driver never frees the interrupt descriptors it allocates. Fix
it by using the resource managed version of irq_alloc_descs().
