Subject: [PATCH 0/6] gpio: replace nocache ioremap functions with devm_platform_ioremap_resource()

From: Bartosz Golaszewski <bgolaszewski@...libre.com>

According to Arnd Bergmann:

"The only architecture that actually has a difference between
ioremap() and ioremap_nocache() seems to be ia64. I would
generally assume that any driver using ioremap_nocache()
that is not ia64 specific should just use ioremap()."

This series converts all users of nocache ioremap variants that aren't
ia64-specific to using devm_platform_ioremap_resource().

Most of these don't call request_mem_region() currently, which
devm_platform_ioremap_resource() does implicitly, so testing would
be appreciated.

Included are two minor fixes for xgene and htc-egpio.

Bartosz Golaszewski (6):
  gpio: xgene: remove redundant error message
  gpio: xgene: use devm_platform_ioremap_resource()
  gpio: em: use devm_platform_ioremap_resource()
  gpio: ath79: use devm_platform_ioremap_resource()
  gpio: htc-egpio: use devm_platform_ioremap_resource()
  gpio: htc-egpio: remove redundant error message
