Series | scsi: ufs: Fix to check the return value of alloc_ordered_workqueue | expand |
Hi, > > In ufshcd_init_clk_gating, alloc_ordered_workqueue may fail and return > NULL. The patch handles error consistent with other invocations in this > module. Not sure that's good enough, as later on we will try to queue work to that workqueue.

In ufshcd_init_clk_gating, alloc_ordered_workqueue may fail and return NULL. The patch handles error consistent with other invocations in this module. Signed-off-by: Aditya Pakki <pakki001@umn.edu> --- drivers/scsi/ufs/ufshcd.c | 2 ++ 1 file changed, 2 insertions(+)
