* Use a special format string specification for the desired output of the array "val" into a sequence. * Adjust two local variables accordingly. This refactoring supersedes the update suggestion "tinydrm: mipi-dbi: Use seq_putc() in mipi_dbi_debugfs_command_show()" from 2017-05-08. https://patchwork.kernel.org/patch/9716119/ Fixes: 02dd95fe316936269a52d6ccb971bb956412b40a ("drm/tinydrm: Add MIPI DBI support") Suggested-by: Joe Perches <j...@perches.com> Signed-off-by: Markus Elfring <elfr...@users.sourceforge.net> --- drivers/gpu/drm/tinydrm/mipi-dbi.c | 7 ++----- 1 file changed, 2 insertions(+), 5 deletions(-) diff --git a/drivers/gpu/drm/tinydrm/mipi-dbi.c b/drivers/gpu/drm/tinydrm/mipi-dbi.c index f4eb412f3604..2670259d1798 100644 --- a/drivers/gpu/drm/tinydrm/mipi-dbi.c +++ b/drivers/gpu/drm/tinydrm/mipi-dbi.c @@ -914,8 +914,7 @@ static int mipi_dbi_debugfs_command_show(struct seq_file *m, void *unused) { struct mipi_dbi *mipi = m->private; u8 cmd, val[4]; - size_t len, i; - int ret; + int len, ret; for (cmd = 0; cmd < 255; cmd++) { if (!mipi_dbi_command_is_read(mipi, cmd)) @@ -944,9 +943,7 @@ static int mipi_dbi_debugfs_command_show(struct seq_file *m, void *unused) continue; } - for (i = 0; i < len; i++) - seq_printf(m, "%02x", val[i]); - seq_puts(m, "\n"); + seq_printf(m, "%*phN\n", len, val); } return 0; -- 2.12.3 _______________________________________________ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel
