Subject: irqchip/qcom: Fix error handling
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=3900dea4cda7c28d7921370bc4d22b08463ed94c;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

irqchip/qcom: Fix error handling

'devm_ioremap()' returns NULL on error, not an error pointer.

Fixes: f20cc9b00c7b ("irqchip/qcom: Add IRQ combiner driver")
