Subject: ARM: OMAP3+: PRM: fix of_irq_get() result check
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d683878dbeab3cd5cd073e40b41f24a4c7f62415;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

ARM: OMAP3+: PRM: fix of_irq_get() result check

of_irq_get() may return 0 as well as a nagative error number on failure
(and never on success), however omap3xxx_prm_late_init() regards 0 as a
valid IRQ -- fix this.
