Subject: MIPS: JZ4740: drop intc debugfs code
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=2aabd281d6c539d738da883b17eb5da25223c2f8;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

MIPS: JZ4740: drop intc debugfs code

The debugfs code becomes a nuisance when attempting to avoid globals,
since the interrupt controller probe function run too early for it to be
safe to create the debugfs files. Drop it.
