Date: Mon, 24 Jan 2022 19:40:50 +0100 From: Greg Kroah-Hartman <gregkh@...uxfoundation.org> To: linux-kernel@...r.kernel.org Cc: Greg Kroah-Hartman <gregkh@...uxfoundation.org>, stable@...r.kernel.org, Lizhi Hou <lizhi.hou@...inx.com>, Sasha Levin <sashal@...nel.org> Subject: [PATCH 5.4 066/320] tty: serial: uartlite: allow 64 bit address From: Lizhi Hou <lizhi.hou@...inx.com> [ 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.
