Message-Id: <1250157001-9645-1-git-send-email-linus.walleij@stericsson.com> Date: Thu, 13 Aug 2009 11:50:01 +0200 From: Linus Walleij <linus.walleij@...ricsson.com> To: Samuel Ortiz <sameo@...ux.intel.com>, linux-kernel@...r.kernel.org Cc: Linus Walleij <linus.walleij@...ricsson.com> Subject: [PATCH 4/5] MFD AB3100 disable irq nosync This will make the worker fire interrupt disable the AB3100 IRQ without sync which resolves a race since the interrupt obviously cannot wait for itself to complete while being handled.
