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- ide=nodma is no longer valid.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).
