      Ludovic Desroches authored
      same issue as commit 7f5ae355:
      "Without DMA_PRIVATE the driver is not able to allocate more than one channel.
      Since it uses dma_get_any_slave_channel that calls private_candidate, the
      second allocation fails at

      The total size of the transfer was wrong in at_xdmac_prep_slave_sg()
      resulting in bad computation of the transfer residue by

      dmaengine: at_xdmac: fix software lockup at_xdmac_tx_status() · 4e097820
      Cyrille Pitchen authored
      According to the Atmel eXtended DMA controller datasheet, requesting a
      DMA transfer flush for a channel is only revelant when this transfer is
      source peripheral synchronized.
      
      So we have to check this condition before requesting a channel flush by
      writing the channel bit into the Global channel SoftWare Flush (GSWF)
      register then waiting for flush to complete by monitoring the end of
      Flush Interrupt Status (FIS) bit in the Channel Interrupt Status (CIS)
      register.
      
      Indeed, for non source peripheral synchronized transfer, writing the
      channel bit into the GSWF register does nothing. Especially, the FIS bit
      is never set into the CIS register. The former code looped forever
      waiting for this bit to be set.

      This driver uses read_relaxed and writel_relaxed to read, write to IO
      memory. the config defines COMPILE_TEST so gets compiled on different archs.
      This causes issue as few archs like x86 etc don't define it.

       "Three main MTD fixes for 3.18:

           restructuring of the m25p80.c driver and the SPI NOR library
           framework, we omitted proper listing of the SPI device IDs.  This
           means m25p80.c wouldn't auto-load (modprobe) properly when built as
           a module.  For now, we duplicate the device IDs into both modules.
      
         - The OMAP / ELM modules were depending on an implicit link ordering.
           Use deferred probing so that the new link order (in 3.18-rc) can
           still allow for successful probing.

      irda: stop calling sk_prot->disconnect() on connection failure · 4cb8c359
      Linus Torvalds authored
      The sk_prot is irda's own set of protocol handlers, so irda should
      statically know what that function is anyway, without using an indirect
      pointer.  And as it happens, we know *exactly* what that pointer is
      statically: it's NULL, because irda doesn't define a disconnect
      operation.
      
      So calling that function is doubly wrong, and will just cause an oops.

      drm/exynos: init kms poll at the end of initialization · 3cb6830a
      Andrzej Hajda authored
      HPD events can be generated by components even if drm_dev is not fully

      be performed at the end of load callback followed directly by forced
      connection detection.

      All KMS objects are destroyed by drm_mode_config_cleanup in proper order
