Subject: [PATCH] media: cec: seco: remove byte handling from smb_word_op
Date: Sat, 12 Mar 2022 07:48:45 -0800 [thread overview]
Message-ID: <20220312154845.1402960-1-trix@redhat.com> (raw)
From: Tom Rix <trix@redhat.com>
smb_word_op() has a parameter data_format that
determines if the data is either a byte or
word. From inspection, smb_word_op() is only
used by the macros smb_wr16() and smb_rd16()
both pass in CMD_WORD_DATA. There is no use of
smb_word_op() that passes in CMD_BYTE_DATA.
So remove the byte handling.
