Subject: [POWERPC] Fix warning in prom_parse.c of_irq_map_oldworld()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=84532c91206bc6748991fb1ae3ba8a1894d339fa;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

[POWERPC] Fix warning in prom_parse.c of_irq_map_oldworld()

This function spews a warning due to possible use of an uninitialized
variable. This can happen on broken device-trees or when called with
a NULL argument. Makes ure we properly fail instead.
