linux-toradex.git/drivers/dma/mpc512x_dma.c, branch v3.10.11 Linux kernel for Apalis and Colibri modules Drivers: dma: remove __dev* attributes. 2013-01-03T23:57:15+00:00 Greg Kroah-Hartman gregkh@linuxfoundation.org 2012-12-21T23:09:59+00:00 4bf27b8b333bcd291664fd0f7d129099d474a23b CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitconst, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

CONFIG_HOTPLUG is going away as an option.  As a result, the __dev*
markings need to be removed.

This change removes the use of __devinit, __devexit_p, __devinitconst,
and __devexit from these drivers.

Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.
