X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=921a880827498e501921bf034012a97e554550d2;p=linux.git

scsi: ufs: ufs-qcom: Drop unnecessary NULL checks

This code path is only called through one function, and the HBA struct is
already accessed in ufshcd_vops_dbg_register_dump() prior to calling so
there is no way for it to be NULL.

Likewise, the print_fn callback is always supplied within this driver and
is always provided.
