ide: ide.c 'clear' fix, update "ide=nodma" documentation
Documentation/kernel-parameters.txt - ide=nodma is no longer valid. drivers/ide/Kconfig - The module is ide-core.ko not ide. drivers/ide/ide.c - It took me a while to figure out what the arguments %d.%d:%d to nodma module parameter ment, so I added a comment to each. - Added a comment to each of the sscanf lines. - There is a bug, if j is 0 it would previously clear all the other bits except the current device, changed in three different places. mask &= (1 << i) should be mask &= ~(1 << i).
