      i2c: qup: use address helper function in read transfer · 0130944b
      Naveen Kaje authored
      qup_i2c_issue_read() derives the address from i2c_msg.
      This called in the read path when I2C_M_RD flag is set.
      Therefore, use the 8 bit address helper function.

      i2c: qup: Fix error handling · fbf9921f
      Sricharan R authored
      Among the bus errors reported from the QUP_MASTER_STATUS register
      only NACK is considered and transfer gets suspended, while
      other errors are ignored. Correct this and suspend the transfer
      for other errors as well. This avoids unnecessary 'timeouts' which
      happens when waiting for events that would never happen when there
      is already an error condition on the bus. Also the error handling
      procedure should be the same for both NACK and other bus errors in
      case of dma mode. So correct that as well.

      sg_set_bug expects that the buf parameter passed in should be from
      lowmem and a valid pageframe. This is not true for pages from
      dma_alloc_coherent which can be carveouts, hence the check fails.
      Change allocation of sg buffers from dma_coherent memory to kzalloc
      to fix the issue. Note that now dma_map/unmap is used to make the
      kzalloc'ed buffers coherent before passing it to the dmaengine.

       "A new bunch of GPIO fixes for v4.7.
      
        This time I am very grateful that Ricardo Ribalda Delgado went in and
        fixed my stupid refcounting mistakes in the removal path for GPIO
        chips.  I had a feeling something was wrong here and so it was.  It
        exploded on OMAP and it fixes their problem.  Now it should be (more)
        solid.
      
        The rest i compilation, Kconfig and driver fixes.  Some tagged for
        stable.
      
        Summary:
      
         - Fix a NULL pointer dereference when we are searching the GPIO
           device list but one of the devices have been removed (struct
           gpio_chip pointer is NULL).
      
         - Fix unaligned reference counters: we were ending on +3 after all
           said and done.  It should be 0.  Remove an extraneous get_device(),
           and call cdev_del() followed by device_del() in gpiochip_remove()
           instead and the count goes to zero and calls the release() function
           properly.
      
         - Fix a compile warning due to a missing #include in the OF/device
           tree portions.
      
         - Select ANON_INODES for GPIOLIB, we're using that for our character
           device.  Some randconfig tests disclosed the problem.
      
         - Make sure the Zynq driver clock runs also without CONFIG_PM enabled
      
         - Fix an off-by-one error in the 104-DIO-48E driver
      
         - Fix warnings in bcm_kona_gpio_reset()"

      Pull SCSI fixes from James Bottomley:
       "Two current fixes:
      
         - one affects Qemu CD ROM emulation, which stopped working after the
           updates in SCSI to require VPD pages from all conformant devices.
      
           Fix temporarily by blacklisting Qemu (we can relax later when they
           come into compliance).
      
         - The other is a fix to the optimal transfer size.  We set up a
           minefield for ourselves by being confused about whether the limits
           are in bytes or sectors (SCSI optimal is in blocks and the queue
           parameter is in bytes).
      
           This tries to fix the problem (wrong setting for queue limits
           max_sectors) and make the problem more obvious by introducing a
           wrapper function"
