Subject: net: fec: return IRQ_HANDLED if fec_ptp_check_pps_event handled it
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=e24ee2780a1d6786b94139ebf95b44c9ae62bf13;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

net: fec: return IRQ_HANDLED if fec_ptp_check_pps_event handled it

fec_ptp_check_pps_event will return 1 if FEC_T_TF_MASK caused
an interrupt. Don't return IRQ_NONE in this case.
