auxdisplay: arm-charlcd: Use readl_poll_timeoutUse readl_poll_timeout_atomic() from instead of usingcustom poll loops.The timeout settings are different, but that shouldn't be much of aproblem.

Mon, 29 Dec 2025 13:03:06 +0000

auxdisplay: arm-charlcd: convert to use device managed APIsThe current probe function of the driver is implemented by usingplain old APIs. As Geert noted, one of the error paths has a mistakethat may lead to a wrong call. Instead of targeting that particularissue, convert the driver to use device managed APIs altogether.It's not needed per se (driver can never be removed once loaded),but it simplifies coding and error handling.Reported-by: Geert Uytterhoeven Closes: https://lore.kernel.org/r/CAMuHMdVquNEoxRQkcBEH0nC+CDuib6o0H6m3CBk3ZN2267LpQw@mail.gmail.comSigned-off-by: Andy Shevchenko List of files: /linux/drivers/auxdisplay/arm-charlcd.c

auxdisplay: arm-charlcd: fix release_mem_region() sizeIt seems like, after the request_mem_region(), the correspondingrelease_mem_region() must take the same size. This was donein (now removed due to previous refactoring) charlcd_remove()but not in the error path in charlcd_probe().Fixes: ce8962455e90 ("ARM: 6214/2: driver for the character LCD found in ARM refdesigns")Signed-off-by: Thomas Fourier Reviewed-by: Geert Uytterhoeven Signed-off-by: Andy Shevchenko List of files: /linux/drivers/auxdisplay/arm-charlcd.c
