Subject: irqchip/mvebu-gicp: Fix an IS_ERR() vs NULL check in probe()
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=c8bb0f00a4886b24d933ffaabcdc09bf9a370dca;p=users%2Fjedix%2Flinux-maple.git

irqchip/mvebu-gicp: Fix an IS_ERR() vs NULL check in probe()

ioremap() never returns error pointers, it returns NULL on error.  Fix the
check to match.

Fixes: 3c3d7dbab2c7 ("irqchip/mvebu-gicp: Clear pending interrupts on init")
