Date: Fri, 13 Jan 2012 00:01:58 -0800 (PST) From: Linus Torvalds <torvalds@...ux-foundation.org> To: Linus Torvalds <torvalds@...ux-foundation.org> cc: Rafał Miłecki <zajec5@...il.com>, Arend van Spriel <arend@...adcom.com>, Larry Finger <Larry.Finger@...inger.net>, Alwin Beukers <alwin@...adcom.com>, Roland Vossen <rvossen@...adcom.com>, "John W. Linville" <linville@...driver.com>, Network Development <netdev@...r.kernel.org>, "Franky (Zhenhui) Lin" <frankyl@...adcom.com> Subject: [PATCH 4/5] brcmsmac: remove PCI suspend/resume from bcma driver From: Linus Torvalds <torvalds@...ux-foundation.org> Date: Thu, 12 Jan 2012 23:36:52 -0800 The brcmsmac driver isn't a PCI driver any more, it's a bcma one. The PCI device has been resumed by the PCI driver (the generic PCI layer, really), we should be resuming just our own driver state. Also add pr_debug() calls to show that we now actually get the suspend/resume events.
