2013-06-24staging: drm/imx: ipuv3-crtc: immediately update crtc->fb in ipu_page_flipPhilipp Zabel
Since commit 8cf1e9811471f2910fa38dc1b28e1789080ba961 ("drm: Add consistency check for page-flipping") drm_mode_page_flip_ioctl contains a WARN_ON that triggers if the .page_flip callback didn't update the crtc->fb pointer to the new framebuffer immediately.

2013-06-24staging: drm/imx: ipu-dmfc: fix bandwidth allocationPhilipp Zabel
The IPU can request up to four pixels per access, which gives four times the bandwidth compared to what the driver currently assumes. After correcting this, we have to increase safety margins for bandwidth requirement calculations.

2013-06-24staging: drm/imx: convert IPU irq driver to irq_domain_add_linearPhilipp Zabel
The IPU has a lot of interrupts. Instead of allocating descs for all of them, register a linear irq domain and create mappings as needed. This was listed in the TODO as a prerequisite to move the IPU driver out of staging.

2013-06-24zram: remove zram_sysfs file (v2)Sergey Senozhatsky
Move zram sysfs code to zram drv and remove zram_sysfs.c file. This gives ability to make static a number of previously exported zram functions, used from zram sysfs, e.g. internal zram zram_meta_alloc/free(). We also can drop zram_drv wrapper functions, used from zram sysfs: e.g. zram_reset_device()/__zram_reset_device() pair. v2: as suggested by Greg K-H, move MODULE description to the bottom of the file.

2013-06-24staging: vt6655: info leak in ioctlDan Carpenter
The SCmdLinkStatus struct has a couple holes. There is one between ->bLink and ->wBSSType, and another between ->abySSID and ->uChannel. I've added a memset() to initialize the struct to zero. Since we don't need to clear abySSID any more so I've removed that memset. It was wrong anyway: abySSID has "SSID_MAXLEN + 2" (34) bytes, not "WLAN_SSID_MAXLEN + 1" (33).

2013-06-24staging: dwc2: fix thinko in dwc2_hc_set_even_odd_frame()Paul Zimmerman
I screwed up the sense of this if() statement while porting our vendor driver to create the dwc2 driver. This caused frame overrun errors on periodic transfers when there were other transfers active in the same (micro)frame. With this fix, the dwc2 driver now works on the Raspberry Pi platform even with the USB Ethernet controller enabled, where before that would cause all USB devices to stop working. Thanks to Ray Jui and Jerry Lin at Broadcom for tracking this down.

2013-06-24staging: line6: avoid __sync_fetch_and_{and,or}Arnd Bergmann
__sync_fetch_and_and and __sync_fetch_and_or are functions that are provided by gcc and depending on the target architecture may be implemented in libgcc, which is not always available in the kernel. This leads to a build failure on ARMv5: drivers/built-in.o: In function `line6_pcm_release': :(.text+0x3bfe80): undefined reference to `__sync_fetch_and_and_4' drivers/built-in.o: In function `line6_pcm_acquire': :(.text+0x3bff30): undefined reference to `__sync_fetch_and_or_4' To work around this, we can use the kernel-provided cmpxchg macro.
