2015-01-30video: fbdev: fix sys_copyareaMans Rullgard
The sys_copyarea() function performs the same operation as cfb_copyarea() but using normal memory access instead of I/O accessors. Since the introduction of sys_copyarea(), there have been two fixes to cfb_copyarea(): - 00a9d699 ("framebuffer: fix cfb_copyarea") - 5b789da8 ("framebuffer: fix screen corruption when copying") This patch incorporates the fixes into sys_copyarea() as well.

2015-01-30video/mmpfb: allow modular buildArnd Bergmann
The frame buffer core can be a module, which means any fb drivers should be able to build as modules too. This turns mmpfb into a tristate option to allow that and fix a possible randconfig build error. drivers/built-in.o: In function `modes_setup': :(.text+0x11b34): undefined reference to `fb_videomode_to_modelist' :(.text+0x11b5c): undefined reference to `fb_videomode_to_var' Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2015-01-30fb: via: turn gpiolib and i2c selects into dependenciesArnd Bergmann
Device driver should not directly select subsystems. In this case we get build warnings like warning: (ARCH_REQUIRE_GPIOLIB && PINCTRL_AT91 && PINCTRL_NOMADIK && MFD_TC6393XB && FB_VIA) selects GPIOLIB which has unmet direct dependencies (ARCH_WANT_OPTIONAL_GPIOLIB || ARCH_REQUIRE_GPIOLIB) which we can avoid using the normal 'depends on' statement. Also, this patch makes it possible for DRM drivers to have a dependency on GPIOLIB without getting circular Kconfig dependencies.

2015-01-27fbdev: fix CVT vertical front and back porch valuesTomi Valkeinen
CVT v1.1 spec says: "the vertical front porch shall in all cases be fixed to 3 lines". The code in fbcvt.c instead sets the _back_ porch to 3 (plus margin). After swapping cvt.v_front_porch and cvt.v_back_porch the resulting timings were in line with CVT timings in VESA DMT spec. The bug seems to be more than 9 years old, but I presume it has not been noticed as usually the video timings come from the EDID or from the timing tables in fbdev, and probably swapped values for vfp and vbp work fine for most of the displays.

2015-01-15video: fbdev: Validate mode timing against monspecDavid Ung
fbmon may generate mode timings that are out of spec of the monitor. eg DELL U2410 has a max clock 170mhz but advertises a resolutions of 1920x1200@60 in its Standard Timings using 2byte code of D1 00. When this is looked up in the DMT table it gives it a 193mhz clock. Although the DELL monitor supports 1920x1200@60, it can only run with reduced timings at 154mhz or DMT id 0x44 which has no STD 2byte code. This patch checks to see if the mode can be supported by the monitor by comparing against monspecs.dclkmax.

This is a static checker fix. We write some binary settings to the sysfs file. One of the settings is the "->startup_profile". There isn't any checking to make sure it fits into the pyra->profile_settings[] array in the profile_activated() function. I added a check to pyra_sysfs_write_settings() in both places because I wasn't positive that the other callers were correct.

2015-01-06r8152: support ndo_features_checkhayeswang
Support ndo_features_check to avoid: - the transport offset is more than the hw limitation when using hw checksum. - the skb->len of a GSO packet is more than the limitation. Signed-off-by: Hayes Wang <hayeswang@realtek.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2015-01-06drm/amdkfd: rewrite kfd_ioctl() according to drm_ioctl()Oded Gabbay
This patch changes kfd_ioctl() to be very similar to drm_ioctl(). The patch defines an array of amdkfd_ioctls, which maps IOCTL definition to the ioctl function. The kfd_ioctl() uses that mapping to call the appropriate ioctl function, through a function pointer. This patch also declares a new typedef for the ioctl function pointer. v2: Renamed KFD_COMMAND_(START|END) to AMDKFD_...

2015-01-06drm/amdkfd: Do copy_to/from_user in general kfd_ioctl()Oded Gabbay
This patch moves the copy_to_user() and copy_from_user() calls from the different ioctl functions in amdkfd to the general kfd_ioctl() function, as this is a common code for all ioctls. This was done according to example taken from drm_ioctl.c Signed-off-by: Oded Gabbay <oded.gabbay@amd.com> Reviewed-by: Christian König <christian.koenig@amd.com>
2015-01-06virtio_pci: document why we defer kfreeMichael S. Tsirkin
The reason we defer kfree until release function is because it's a general rule for kobjects: kfree of the reference counter itself is only legal in the release function. Previous patch didn't make this clear, document this in code. Cc: stable@vger.kernel.org Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2015-01-06virtio_pci: defer kfree until release callbackSasha Levin
A struct device which has just been unregistered can live on past the point at which a driver decides to drop it's initial reference to the kobject gained on allocation. This implies that when releasing a virtio device, we can't free a struct virtio_device until the underlying struct device has been released, which might not happen immediately on device_unregister(). Unfortunately, this is exactly what virtio pci does: it has an empty release callback, and frees memory immediately after unregistering the device. This causes an easy to reproduce crash if CONFIG_DEBUG_KOBJECT_RELEASE it enabled. To fix, free the memory only once we know the device is gone in the release callback.
