From: Lizhi Hou <lizhi.hou@xilinx.com> stable inclusion from linux-4.19.226 commit 628c2372100a118f5500f596c5c941720adbcc28 -------------------------------- [ 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.
