hwmon: replace snprintf in show functions with sysfs_emit
coccicheck complains about the use of snprintf() in sysfs show functions. drivers/hwmon/ina3221.c:701:8-16: WARNING: use scnprintf or sprintf This results in a large number of patch submissions. Fix it all in one go using the following coccinelle rules. Use sysfs_emit instead of scnprintf or sprintf since that makes more sense. @depends on patch@ identifier show, dev, attr, buf; @@ ssize_t show(struct device *dev, struct device_attribute *attr, char *buf) { <... return - snprintf(buf, \( PAGE_SIZE \| PAGE_SIZE - 1 \), + sysfs_emit(buf, ...); ...> } @depends on patch@ identifier show, dev, attr, buf, rc; @@ ssize_t show(struct device *dev, struct device_attribute *attr, char *buf) { <... rc = - snprintf(buf, \( PAGE_SIZE \| PAGE_SIZE - 1 \), + sysfs_emit(buf, ...); ...> } While at it, remove unnecessary braces and as well as unnecessary else after return statements to address checkpatch warnings in the resulting patch.
