driver core: Drop helper devm_platform_ioremap_resource_wc()
Since the macro was introduced in 2019 (commit bb6243b4f73d ("drivers: platform: provide devm_platform_ioremap_resource_wc()") there is only a single user which hardly justifies the function for the small task it provides. So drop the helper and open-code it in the only user. Adapt the non-wc case accordingly. For a all-mod-config build on amd64 this change introduces the following changes according to bloat-o-meter: add/remove: 0/1 grow/shrink: 1/0 up/down: 20/-252 (-232) Function old new delta devm_platform_ioremap_resource_wc 252 - -252 sram_probe 796 816 +20 Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> Link: https://lore.kernel.org/r/20210525103711.956438-1-u.kleine-koenig@pengutronix.de Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
