Subject: scsi: rewrite print_sg_io_buffer using printstr_ex(QUOTE_FORCE_HEX)
X-Git-Tag: v4.16~85
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=601a324df2e825289801181f978367d754dd8f83;p=strace

scsi: rewrite print_sg_io_buffer using printstr_ex(QUOTE_FORCE_HEX)

As printstr_ex has got QUOTE_FORCE_HEX flag support, there is no need
to implement it manually any longer.

* scsi.c (print_uchar): Remove.
(print_sg_io_buffer): Rewrite using printstr_ex(QUOTE_FORCE_HEX).
