Since commit 188db4435ac6 ("usb: gadget: s3c: use platform resources"), 'request_mem_region()' and 'ioremap()' are no more used, so they don't need to be undone in the error handling path of the probe and in the removre function. Remove these calls and the unneeded 'rsrc_start' and 'rsrc_len' global variables. Fixes: 188db4435ac6 ("usb: gadget: s3c: use platform resources") Signed-off-by: Christophe JAILLET <christophe.jaillet@wanadoo.fr> --- the 'err' label is used only to reduce the diff size of this patch. It is removed in the following patch. v2: Fix a stupid error in the hash in Fixes: --- drivers/usb/gadget/udc/s3c2410_udc.c | 14 +++----------- 1 file changed, 3 insertions(+), 11 deletions(-)
