      staging: drm/imx: Add parallel display support · 19022aaa
      Sascha Hauer authored
      This adds support for parallel displays for i.MX. It consists
      of a drm encoder/connector pair which eventually passes EDID
      data from the devicetree to the drm core.

      Staging: bcm: Remove typedef for _stIM_sfHostNotify and call directly. · f34170c7
      Kevin McKinney authored
      This patch removes typedef for _stIM_sfHostNotify,
      changes the name of the struct from
      _stIM_sfHostNotify to bcm_stim_sfhostnotify.
      In addition, any calls to the following typedef
      "stIM_sfHostNotify" are changed to call the
      struct directly.

      Wei Yongjun authored
      In case of error, the function clk_get() returns ERR_PTR()
      and never returns NULL pointer. The NULL test in the error
      handling should be replaced with IS_ERR().

      staging: sbe-2t3e3: use -ve error return codes in dc_init_descriptor_list · a00979cc
      Devendra Naga authored
      the dc_init_descriptor_list actually returns a +ve error return codes,
      which is abnormal as other functions in kernel return -ve error codes on
      failure. so replace the return codes of this function with -ve values
      to make the consistency with the other functions in kernel.
      
      Also make the dc_init_descriptor_list static as its never called
      anywhere except in this file and move the function prototype from the
      headerfile into the c file as its referred only in this c file.

      compared with higher limit for less than condition as well,

      In response to "usbip detach -p [port_number]" user command,vhci_shutdown_connection() gets
      executed which kills tcp_tx,tcp_rx kernel threads but doesn't set thread pointers to NULL.
      so, at the time of vhci_hcd removal vhci_shutdown_connection() again tries to kill kernel
      threads which are already killed.
