stable inclusion from stable-v6.6.3 commit d5b648567bfb6a1737fb5dda8a87bfde4916dd8c category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I8LBQP
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
commit 57925e16c9f7d18012bcf45bfa658f92c087981a upstream.
For the t7 and older SoC families, the CMD_CFG_ERROR has no effect. Starting from SoC family C3, setting this bit without SG LINK data address will cause the controller to generate an IRQ and stop working.
To fix it, don't set the bit CMD_CFG_ERROR anymore.
