Correct - but that pull request was obsolete anyway as one of the driver
patches had independentaly submitted to both me and gregkh and you pulled
Greg's version yesterday.

I spun a new tree which again is at:

  git://ftp.linux-mips.org/pub/scm/upstream-linus.git upstream

Please pull, thanks!

    VIDEO: Correct use of request_region/request_mem_region
    
    request_region should be used with release_region, not request_mem_region.
    
    Geert Uytterhoeven pointed out that in the case of drivers/video/gbefb.c,
    the problem is actually the other way around; request_mem_region should be
    used instead of request_region.
    
    The semantic patch that finds/fixes this problem is as follows:
    (http://coccinelle.lip6.fr/)
    
    // <smpl>
    @r1@
    expression start;
    @@
    
    request_region(start,...)
    
    @b1@
    expression r1.start;
    @@
    
    request_mem_region(start,...)
    
    @depends on !b1@
    expression r1.start;
    expression E;
    @@
    
    - release_mem_region
    + release_region
      (start,E)
    // </smpl>

    SPI: spi_txx9: Fix bit rate calculation
    
    TXx9 SPI bit rate is calculated by:
            fBR = (spi-baseclk) / (n + 1)
    Fix calculation of min_speed_hz, max_speed_hz and n.
