2012-11-07isdn: Make CONFIG_ISDN depend on CONFIG_NETDEVICESLee Jones
It doesn't make much sense to enable ISDN services if you don't intend to connect to a network. Therefore insisting that ISDN depends on NETDEVICES seems logical. We can then remove any guards mentioning NETDEVICES inside all subordinate drivers. This also has the nice side-effect of fixing the warning below when ISDN_I4L && !CONFIG_NETDEVICES at compile time. This patch fixes: drivers/isdn/i4l/isdn_common.c: In function ‘isdn_ioctl’: drivers/isdn/i4l/isdn_common.c:1278:8: warning: unused variable ‘s’ [-Wunused-variable] Cc: Karsten Keil <isdn@linux-pingi.de> Cc: netdev@vger.kernel.org Signed-off-by: Lee Jones <lee.jones@linaro.org> Signed-off-by: David S.

2012-11-07mmc: sdhci: fix IS_ERR() checking of regulator_get()Kevin Liu
There are two problems here: The check for vmmc was printing an unnecessary pr_info() when host->vmmc is NULL. The intent of the check for vqmmc was to only remove UHS if we have a regulator that doesn't support the required voltage, but since IS_ERR() doesn't catch NULL, we were actually removing UHS modes if vqmmc isn't present at all -- since it isn't present for most users, this breaks UHS for them. This patch fixes that UHS regression in 3.7-rc1.

In https://bugzilla.kernel.org/show_bug.cgi?id=48981 Peter reported that /proc/bus/pci/??/??.? does not work for 3.6. This is because the device configuration space registers are not accessible if the corresponding parent bridge is suspended or the device is put into D3cold state. This is the same as /sys/bus/pci/devices/0000:??:??.?/config access issue. So the function used to solve sysfs issue is used to solve this issue.

2012-11-05pinctrl: SPEAr: Don't update all non muxreg bits on pinctrl_disableViresh Kumar
Not all bits of a register are used for pinctrl in SPEAr. So only update bits relevant to pinctrl using muxreg->mask. Signed-off-by: Viresh Kumar <viresh.kumar@linaro.org> Acked-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2012-11-04xen/hypercall: fix hypercall fallback code for very old hypervisorsJan Beulich
While copying the argument structures in HYPERVISOR_event_channel_op() and HYPERVISOR_physdev_op() into the local variable is sufficiently safe even if the actual structure is smaller than the container one, copying back eventual output values the same way isn't: This may collide with on-stack variables (particularly "rc") which may change between the first and second memcpy() (i.e. the second memcpy() could discard that change). Move the fallback code into out-of-line functions, and handle all of the operations known by this old a hypervisor individually: Some don't require copying back anything at all, and for the rest use the individual argument structures' sizes rather than the container's.
