From 7af97effb3f5a374482179aca490b5038de56fa6 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Thu, 30 Sep 2010 08:25:42 -0300 Subject: [PATCH] V4L/DVB: Deprecate cpia driver (used for parallel port webcams) cpia driver were re-written inside gspca driver, for USB devices. The only functionality that were not migrated is the support for parallel port, as: 1) the developer didn't find any hardware; 2) it doesn't seem important to keep support for a parallel port webcam, as this is an obsolete technology; 3) the changes at gspca for it to work with parallel port would be very large; 4) this driver still uses BKL. So, let's move it to drivers/staging and label it to die at 2.6.38, if nobody cares enough to port parallel port support to gspca or to create a new driver that uses the same gspca-cpia sub-driver.
