X-Git-Tag: v6.1-rc5~1819^2~4
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=83d9b7e3955d32d3e4e3321029f655716cb21c99;p=platform%2Fkernel%2Flinux-starfive.git

mfd: ezx-pcap: Use generic_handle_irq_safe().

Instead of manually disabling interrupts before invoking use
generic_handle_irq_safe() which can be invoked with enabled and disabled
interrupts.
