Merge tag 'gpio-fixes-for-v6.0-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux
Pull gpio fixes from Bartosz Golaszewski:
- fix a NULL-pointer dereference at driver unbind and a potential
resource leak in error path in gpio-mockup
- make the irqchip immutable in gpio-ftgpio010
- fix dereferencing a potentially uninitialized variable in gpio-tqmx86
- fix interrupt registering in gpiolib's character device code
* tag 'gpio-fixes-for-v6.0-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux:
gpiolib: cdev: Set lineevent_state::irq after IRQ register successfully
gpio: tqmx86: fix uninitialized variable girq
gpio: ftgpio010: Make irqchip immutable
gpio: mockup: Fix potential resource leakage when register a chip
gpio: mockup: fix NULL pointer dereference when removing debugfs
