staging: et131x: zero allocation of fbr to prevent random address access
If et131x_rx_dma_memory_alloc() allocates rx_ring->fbr[0] but fails to
allocate rx_ring->fbr[1], this leaves fbr[0]->ring_virtaddr with the
possibility of being accessed in et131x_rx_dma_memory_free() as it
contains a random value, potentially causing an oops.
Fix this by zeroing the fbr memory on allocation. Subsequent frees of
this fbr memory explicitly zeros the ring_virtaddr value.
imx-drm: imx-drm-core: add basic suspend/resume support
HDMI currently stops working after a system suspend/resume cycle. The
cause is that the mode setting states in hardware gets lost and isn't
restored across the suspend/resume cycle.
The patch adds a very basic suspend/resume support to imx-drm driver,
and calls drm_helper_resume_force_mode() in .resume hook to restore the
mode setting states, so that HDMI can continue working after a system
suspend/resume cycle.
Since the suspend/resume hook can be called with drm_device pointer
being NULL from driver data, we need a check on the pointer in the
hooks. And to avoid using a stale pointer from driver data, it also
clears driver data in .unload hook.
imx-drm: ipuv3-plane: remove function ipu_plane_dpms()
All those ipu_*_put() calls in ipu_plane_dpms() are unnecessary,
because the only occurrence of ipu_plane_dpms() with 'mode' not being
DRM_MODE_DPMS_ON is in function ipu_disable_plane(), which already
has a ipu_plane_put_resources() call to put those ipu resources right
after ipu_plane_dpms().
So with those redundant ipu_*_put() calls removed from ipu_plane_dpms(),
the only left code in the function is ipu_plane_enable|disable(). Thus,
we can just call ipu_plane_enable|disable() as needed directly and
remove the ipu_plane_dpms() function completely.

staging: unisys: fix IO memory copy in channel.h
The function ULTRA_check_channel_client() was recently patched to use
ioread8_rep(). Unfortunately the parameters were incorrectly ordered, and this
causes the function to fail and the guest to not boot.
This patch switches the parameters around and uses memcpy_fromio() instead,
which is clearer since a structure is being copied, not an array, and it
fixes the error message printout later in the function that was using the UUID
value in the channel, rather than the value copied from the channel, which
causes a misleading error to be reported.

Staging: lustre: Replace GOTO macro with necessary code
The GOTO macro is neither standard in Linux nor does its definiton
contain much useful code. Hence GOTO can be replaced with useful
parts of its definition. In a statement like GOTO(label, rc), the
replacing code will be goto label if rc is a constant or a variable.
But in cases like GOTO(label, e) where e is an assignment statement,
both assignment and goto statements are kept.

patch was used:
