The patch in question was for sh_mobile_ceu_camera.c - not for pxa, and 
even though that one doesn't include any asm headers, as you see, it is 
also tied pretty closely with respective platform code.

As for including asm headers in pxa_camera.c - it wouldn't be easy to get 
rid of them, one of the main obstacles is the use of the pxa-specific 
dma-channel handling API.
