serial: sh-sci: Make probe fail for ports that exceed the maximum count

2012-06-13T01:22:10Z

The driver supports a maximum number of ports configurable at compile time. Make sure the probe() method fails when registering a port that exceeds the maximum instead of returning success without registering the port. This fixes a crash at system suspend time, when the driver tried to suspend a non-registered port using the UART core. Signed-off-by: Laurent Pinchart Signed-off-by: Paul Mundt

serial: sh-sci: Fix probe error paths

2012-06-13T01:22:08Z

When probing fails, the driver must not try to cleanup resources that have not been initialized. Fix this. Signed-off-by: Laurent Pinchart Signed-off-by: Paul Mundt

serial/amba-pl011: move custom pin control to driver

2012-06-12T22:41:44Z

We had a boot regression in Ux500 in the merge window because two orthogonal pin control schemes for the PL011 were merged at the same time: - One using the .init() and .exit() hooks into the platform for Ux500 putting the pins into default vs sleep state respectively as the port was started/stopped. commit a09806607fd20bed2f8c41fe22793386790a14aa "ARM: ux500: switch to using pinctrl for uart0" - One hogging the default setting at PL011 probe() commit 258e055111d3cde2607e0d04eb91da2f7a59b591 "serial: amba-pl011: adopt pinctrl support" To get a solution that works for both let's scrap the stuff in the platform callbacks, instead have the driver itself select default and sleep states when the port is started/stopped. Hopefully this works for all clients. Platform callbacks are bad for device tree migration anyway, so this rids us of another problem in Ux500.

tty: Revert the tty locking series, it needs more work

2012-06-02T22:21:43Z

This reverts the tty layer change to use per-tty locking, because it's not correct yet, and fixing it will require some more deep surgery. The main revert is d29f3ef39be4 ("tty_lock: Localise the lock"), but there are several smaller commits that built upon it, they also get reverted here. The list of reverted commits is: fde86d310886 - tty: add lockdep annotations 8f6576ad476b - tty: fix ldisc lock inversion trace d3ca8b64b97e - pty: Fix lock inversion b1d679afd766 - tty: drop the pty lock during hangup abcefe5fc357 - tty/amiserial: Add missing argument for tty_unlock() fd11b42e3598 - cris: fix missing tty arg in wait_event_interruptible_tty call d29f3ef39be4 - tty_lock: Localise the lock The revert had a trivial conflict in the 68360serial.c staging driver that got removed in the meantime.

Pull MIPS updates from Ralf Baechle: "The whole series has been sitting in -next for quite a while with no complaints. The last change to the series was before the weekend the removal of an SPI patch which Grant - even though previously acked by himself - appeared to raise objections. So I removed it until the situation is clarified. Other than that all the patches have the acks from their respective maintainers, all MIPS and x86 defconfigs are building fine and I'm not aware of any problems introduced by this series. Among the key features for this patch series is a sizable patchset for Lantiq which among other things introduces support for Lantiq's flagship product, the FALCON SOC. It also means that the opensource developers behind this patchset have overtaken Lantiq's competing inhouse development team that was working behind closed doors. Less noteworthy the ath79 patchset which adds support for a few more chip variants, cleanups and fixes. Finally the usual dose of tweaking of generic code." Fix up trivial conflicts in arch/mips/lantiq/xway/gpio_{ebu,stp}.c where printk spelling fixes clashed with file move and eventual removal of the printk. * 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus: (81 commits) MIPS: lantiq: remove orphaned code MIPS: Remove all -Wall and almost all -Werror usage from arch/mips.

Pull arm-soc clock driver changes from Olof Johansson: "The new clock subsystem was merged in linux-3.4 without any users, this now moves the first three platforms over to it: imx, mxs and spear. The series also contains the changes for the clock subsystem itself, since Mike preferred to have it together with the platforms that require these changes, in order to avoid interdependencies and conflicts."
