ARM/etm/sysrq: fix inconstistent help message of sysrq key
Currently help message of /proc/sysrq-trigger highlights its upper-case characters, like below: SysRq : HELP : loglevel(0-9) reBoot Crash terminate-all-tasks(E) memory-full-oom-kill(F) kill-all-tasks(I) ... this would confuse user trigger sysrq by upper-case character, which is inconsistent with the real lower-case character registed key. This inconsistent help message will also lead more confused when 26 upper-case letters put into use in future. This patch fix arm etm sysrq key: "etm-buffer-dump(v)" (This patch also add "-" to separate each sysrq key help word, instead of spaces) Signed-off-by: zhangwei(Jovi) <jovi.zhangwei@huawei.com> Acked-by: Randy Dunlap <rdunlap@infradead.org> Cc: Russell King <linux@arm.linux.org.uk> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
