flags only use was in spin_lock_irqsave/spin_lock_irgrestore pairs, no need to redeclare for each one. drivers/char/esp.c:1599:17: warning: symbol 'flags' shadows an earlier one drivers/char/esp.c:1517:16: originally declared here drivers/char/esp.c:1615:17: warning: symbol 'flags' shadows an earlier one drivers/char/esp.c:1517:16: originally declared here drivers/char/esp.c:1631:17: warning: symbol 'flags' shadows an earlier one drivers/char/esp.c:1517:16: originally declared here Signed-off-by: Harvey Harrison <harvey.harrison@gmail.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
