Subject: nfc: nxp-nci: Remove i2c client gpio irq configuration
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=be103b714e4e6ad7316b0cb9b9d473ddedaf4ad6;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

nfc: nxp-nci: Remove i2c client gpio irq configuration

gpio irq is already configured by the core i2c layers
when reaching the probe function.
