Zheyu Ma reported this crash in the sm712fb driver when reading three bytes from the framebuffer: BUG: unable to handle page fault for address: ffffc90001ffffff RIP: 0010:smtcfb_read+0x230/0x3e0 Call Trace: vfs_read+0x198/0xa00 ? do_sys_openat2+0x27d/0x350 ? __fget_light+0x54/0x340 ksys_read+0xce/0x190 do_syscall_64+0x43/0x90 Fix it by removing the open-coded endianess fixup-code and by moving the pointer post decrement out the fb_readl() function.
