Actually I think it's the case.
And the driver bug fix is here :
  a52db659c79c ("spi: pxa2xx: Fix cs_change management")

And please don't apply this as there are 2 other LCDs which are affected by the
same issue and reported by Andrea, for which I had not correlated the issue
until yesterday, so I'll have to respin this 2 others files, namely :
 - drivers/video/backlight/corgi_lcd.c.
 - drivers/video/backlight/tosa_lcd.c.

There 2 other candidates I won't touch as they are not under my maintainance,
and I have no way to test them :
 - ili922x.c
 - ltv350qv.c

Thanks, but there will be a v2 with exactly the same fix in 3 files.

Cheers.
