4.19-stable review patch. If anyone has any objections, please let me know.
------------------
From: Colin Ian King <colin.king@xxxxxxxxxxxxx>
commit 13c45007e0a87e912da21223599583fdea677914 upstream.
Passing string ch_data_type[i].name as the format specifier is
potentially hazardous because it could (although very unlikely to)
have a format specifier embedded in it causing issues when parsing
the non-existent arguments to these. Follow best practice by using
the "%s" format string for the string.
Cleans up clang warning:
format string is not a string literal (potentially insecure) [-Wformat-security]
Fixes: e7f2b70fd3a9 ("staging: most: replace multiple if..else with table lookup")
