[PATCH 0/2] Add IRQ check to the Meson MMC/SD drivers

Here are 2 patches against the 'fixes' branch of Ulf Hansson's 'mmc.git' repo.
The affected drivers call platform_get_irq() but forget to check for the error
case and blithely pass the negative error codes to devm_request_threaded_irq()
(which takes *unsigned* IRQ #). Now stop calling devm_request_threaded_irq()
with the invalid IRQ #s!

  mmc: meson-mx-sdhc: add IRQ check
  mmc: meson-mx-sdio: add IRQ check
