mainline inclusion from mainline-v5.17-rc1 commit ecc7169d4f73 category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I5AFY1 CVE: NA
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?i...
----------------------------------------------------------------------
The value of qos should be reset after flr resetting or device resetting. So set the max of qos value for every function. Then update the value of qos when user writing the alg_qos.
