Message-Id: <20240319054527.1581299-4-lizhijian@fujitsu.com> Date: Tue, 19 Mar 2024 13:45:27 +0800 From: Li Zhijian <lizhijian@...itsu.com> To: linux-kernel@...r.kernel.org Cc: Li Zhijian <lizhijian@...itsu.com>, Jiri Kosina <jikos@...nel.org>, Benjamin Tissoires <benjamin.tissoires@...hat.com>, linux-input@...r.kernel.org Subject: [PATCH v4 4/4] HID: corsair,lenovo: Convert sprintf() family to sysfs_emit() family Per filesystems/sysfs.rst, show() should only use sysfs_emit() or sysfs_emit_at() when formatting the value to be returned to user space. coccinelle complains that there are still a couple of functions that use snprintf(). Convert them to sysfs_emit(). sprintf() and scnprintf() will be converted as well if they have. Generally, this patch is generated by make coccicheck M=<path/to/file> MODE=patch \ COCCI=scripts/coccinelle/api/device_attr_show.cocci No functional change intended CC: Jiri Kosina <jikos@...nel.org> CC: Benjamin Tissoires <benjamin.tissoires@...hat.com> CC: linux-input@...r.kernel.org Signed-off-by: Li Zhijian <lizhijian@...itsu.com> --- This is a part of the work "Fix coccicheck device_attr_show warnings"[1] Split them per subsystem so that the maintainer can review it easily [1] https://lore.kernel.org/lkml/20240116041129.3937800-1-lizhijian@fujitsu.com/ --- drivers/hid/hid-corsair.c | 4 ++-- drivers/hid/hid-lenovo.c | 23 ++++++++++------------- 2 files changed, 12 insertions(+), 15 deletions(-) diff --git a/drivers/hid/hid-corsair.c b/drivers/hid/hid-corsair.c index 8c895c820b67..702f50e9841d 100644 --- a/drivers/hid/hid-corsair.c +++ b/drivers/hid/hid-corsair.c @@ -298,7 +298,7 @@ static ssize_t k90_show_macro_mode(struct device *dev, goto out;
