/* Linux driver for Philips webcam
(C) 2004-2006 Luc Saillard (luc@saillard.org)
NOTE: this version of pwc is an unofficial (modified) release of pwc & pcwx
driver and thus may have bugs that are not present in the original version.
Please send bug reports and support requests to <luc@saillard.org>.
The decompression routines have been implemented by reverse-engineering the
Nemosoft binary pwcx module. Caveat emptor.

[media] pwc: Use one shared usb command buffer The pwc driver used to: 1. kmalloc a buffer 2. memcpy data to send over usb there 3. do the usb_control_msg call (which does not work with data on the stack) 4. free the buffer For every usb command send. This patch changes the code to instead malloc a buffer for this purpose once and use it everywhere.
