6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Kai Ye yekai13@huawei.com
[ Upstream commit b40b62ed7b0ffe8eb2e6fe8bcfb47027c9a93e93 ]
The last register logic and different register logic are combined. Use "u32" instead of 'int' in the regs function input parameter to simplify some checks.
