Subject: regmap: irq: Enable irq retriggering for nested irqs
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=58a5336292abb032085d621810c3c41c9cea36ed;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

regmap: irq: Enable irq retriggering for nested irqs

When nested interrupts are handled with regmap irq framework, we need to
mark the interrupts to be resend for pending interrupts on enable_irq.
Else the events might be lost for nested irqs.
