Subject: genirq/debugfs: Remove pointless NULL pointer check
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=c2ce34c0a0e5187195ecade872be950d2611ba68;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

genirq/debugfs: Remove pointless NULL pointer check

debugfs_remove() has it's own NULL pointer check. Remove the conditional
and make irq_remove_debugfs_entry() an inline helper
