From: Lizhi Hou <lizhi.hou@xilinx.com> stable inclusion from stable-v5.10.94 commit 8409d2394cca3cef7f625d8a74702f1d600eee3e bugzilla: https://gitee.com/openeuler/kernel/issues/I531X9 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=... -------------------------------- [ Upstream commit 3672fb65155530b5eea6225685c75329b6debec3 ] The base address of uartlite registers could be 64 bit address which is from device resource. When ulite_probe() calls ulite_assign(), this 64 bit address is casted to 32-bit. The fix is to replace "u32" type with "phys_addr_t" type for the base address in ulite_assign() argument list.
