mainline inclusion from mainline-v6.6-rc7 commit 4abbd2e3c1db671fa1286390f1310aec78386f1d category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/IAGKJU
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?i...
-------------------------------------------
In the smc_listen_work(), if smc_listen_prfx_check() failed, the real reason: SMC_CLC_DECL_DIFFPREFIX was dropped, and SMC_CLC_DECL_NOSMCDEV was returned.
Althrough this is also kind of SMC_CLC_DECL_NOSMCDEV, but return the real reason is much friendly for debugging.
