gpio fixes for v6.2-rc6
- fix the -c option in the gpio-event-mode user-space example program - fix the irq number translation in gpio-ep93xx and make its irqchip immutable - add a missing spin_unlock in error path in gpio-mxc - fix a suspend breakage on System76 and Lenovo Gen2a introduced in GPIO ACPI -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEFp3rbAvDxGAT0sefEacuoBRx13IFAmPUKckACgkQEacuoBRx 13KjuQ//fL9MagRQVsE85SVhhMsjmTTbXnvGJOIT0iTTvqgh9DACX9m6EDQQ/8Kd bKuciI0h2zO5xt/fZPAyJWgGw0w3qvld7f3f6KQE60X4MRyckyZB9xEyHnvuUs+X v0SiH8rLm+znezFXFiIB3lq004T9DU+wxUCaSq4WH1eE7eqKP8ZXhg2sLUgiskiY c1Albv2X0xM4duLmPBK4vsXV2x35yj5qS0qkIymezff2sQekzb3TOZsaS7Doznex cKr2OvJR/VuH4SMv+uIoKjsVKzdvtP/6hBKJtTH5i1krzNsBW/S+/7odwxzdxPVU EgQc5I7/ubV7FP3Jo3ThO3exTFyd50hl4jKmrkrzzFpeh2xZ2eKU/AD8/MNsPVuA KAoBUxHnoJfdZuUNL0Cmf1pTmzZbS80qntznzO700QtBaIxS/6redfJ8CKUK4Iy8 f491K3SbzpXzRAjVMBv8ua7JrB8MT82IKxbeXd1bellGrLaNuMzj1Yd8XhWlepnQ wZxMSo3457FpOghiiMM3YnLSCcpbs4WU8VV/NMCc8jfS14oq7gA26EalQLPwKeCF 5c+UMAZ95gafJwPjuZcDJcRCGpDlhqPawRBo5cDVUlSokh1PSmPhcGNtE8XKUKlE fHyd6WEYn8AzXnf3PMceiuJYCADs8wtg87GHKuLF1PPXmcqM4C8= =wh3L -----END PGP SIGNATURE----- Merge tag 'gpio-fixes-for-v6.2-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux Pull gpio fixes from Bartosz Golaszewski: - fix the -c option in the gpio-event-mode user-space example program - fix the irq number translation in gpio-ep93xx and make its irqchip immutable - add a missing spin_unlock in error path in gpio-mxc - fix a suspend breakage on System76 and Lenovo Gen2a introduced in GPIO ACPI * tag 'gpio-fixes-for-v6.2-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux: tools: gpio: fix -c option of gpio-event-mon gpio: ep93xx: remove unused variable gpio: ep93xx: Make irqchip immutable gpio: ep93xx: Fix port F hwirq numbers in handler gpio: mxc: Unlock on error path in mxc_flip_edge() gpiolib-acpi: Don't set GPIOs for wakeup in S3 mode
