Michal Sojka 270579d95f uio_mf624: Align memory regions to page size and set correct offsets ... mf624 card has its registers not aligned to pages. Since commit b655028795 ("uio: we cannot mmap unaligned page contents") mmap()ing mf624 registers fails, because now the uio drivers must set uio_mem->addr to be page-aligned. We align the address here and set the newly introduced offs field to the offset of the mf264 registers within the page so that userspace can find the address of the mmap()ed register by reading /sys/class/uio/uio?/maps/map?/offset. Tested with real mf624 card. Signed-off-by: Michal Sojka <sojkam1@fel.cvut.cz> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>		2017-04-08 18:13:28 +02:00
