firewire: Convert snprintf/sprintf to sysfs_emit
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(). > drivers/firewire/core-device.c:326:8-16: WARNING: please use sysfs_emit or sysfs_emit_at No functional change intended Signed-off-by: Li Zhijian <lizhijian@fujitsu.com> Link: https://lore.kernel.org/r/20240122053942.80648-2-lizhijian@fujitsu.com Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp>
