Merge tag 'gpio-fixes-for-v6.18-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux

Pull gpio fixes from Bartosz Golaszewski:

 - fix regressions in regmap cache initialization in gpio-104-idio-16
   and gpio-pci-idio-16

 - configure first 16 GPIO lines of the IDIO-16 as fixed outputs

 - fix duplicated IRQ mapping that can lead to an RCU stall in gpio-ljca

 - fix printf formatters passed to dev_err() and make failure to set
   debounce period non fatal
