      mtd: mpc5121_nfc: Fix module autoload for OF platform driver · 7446076e
      Luis de Bethencourt authored
      This platform driver has a OF device ID table but the OF module
      alias information is not created so module autoloading won't work.

      jffs2: remove unnecessary new_valid_dev check · 1bc81eee
      Yaowei Bai authored
      As new_valid_dev always returns 1, so !new_valid_dev check is not
      needed, remove it.

      mtd: nand: pxa3xx-nand: switch to dmaengine · 8f5ba31a
      Robert Jarzmik authored
      Now pxa architecture has a dmaengine driver, remove the access to direct
      dma registers in favor of the more generic dmaengine code.
      
      This should be also applicable for mmp and orion, provided they work in
      device-tree environment.
      
      This patch also removes the previous hack which was necessary to make
      the driver work in a devicetree environment.

      blk: rq_data_dir() should not return a boolean · 10fbd36e
      Linus Torvalds authored
      rq_data_dir() returns either READ or WRITE (0 == READ, 1 == WRITE), not
      a boolean value.
      
      Now, admittedly the "!= 0" doesn't really change the value (0 stays as
      zero, 1 stays as one), but it's not only redundant, it confuses gcc, and
      causes gcc to warn about the construct
      
          switch (rq_data_dir(req)) {
              case READ:
                  ...
              case WRITE:
                  ...
      
      that we have in a few drivers.
      
      Now, the gcc warning is silly and stupid (it seems to warn not about the
      switch value having a different type from the case statements, but about
      _any_ boolean switch value), but in this case the code itself is silly
      and stupid too, so let's just change it, and get rid of warnings like
      this:
      
        drivers/block/hd.c: In function ‘hd_request’:
        drivers/block/hd.c:630:11: warning: switch condition has boolean value [-Wswitch-bool]
           switch (rq_data_dir(req)) {
      
      The odd '!= 0' came in when "cmd_flags" got turned into a "u64" in
      commit 5953316d ("block: make rq->cmd_flags be 64-bit") and is
      presumably because the old code (that just did a logical 'and' with 1)
      would then end up making the type of rq_data_dir() be u64 too.
      
      But if we want to retain the old regular integer type, let's just cast
      the result to 'int' rather than use that rather odd '!= 0'.
