Subject: scsi: ufs: core: Fix ufshcd_is_ufs_dev_busy() and ufshcd_eh_timed_out()
X-Git-Tag: v6.14-rc5~26^2~3
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=4fa382be430421e1445f9c95c4dc9b7e0949ae8a;p=thirdparty%2Flinux.git

scsi: ufs: core: Fix ufshcd_is_ufs_dev_busy() and ufshcd_eh_timed_out()

ufshcd_is_ufs_dev_busy(), ufshcd_print_host_state() and
ufshcd_eh_timed_out() are used in both modes (legacy mode and MCQ mode).
hba->outstanding_reqs only represents the outstanding requests in legacy
mode. Hence, change hba->outstanding_reqs into scsi_host_busy(hba->host) in
these functions.
