Subject: [PATCH] Drivers:staging:ozwpan Fixed sparse context imbalance warning
Date: Fri, 28 Feb 2014 08:57:02 -0800	[thread overview]
Message-ID: <1393606622-7549-1-git-send-email-surendra.tux@gmail.com> (raw)

Sparse warns about -
drivers/staging/ozwpan/ozproto.c:797:6: warning: context imbalance in 'oz_polling_lock_bh' - wrong count at exit
drivers/staging/ozwpan/ozproto.c:802:6: warning: context imbalance in 'oz_polling_unlock_bh' - unexpected unlock
so added __acquires() and __releases().
