Revision 0da2f0f164f098bb4447c714b552ac1681b2d6e8 authored by Yoann Padioleau on 06 July 2007, 09:39:56 UTC, committed by Linus Torvalds on 06 July 2007, 17:23:43 UTC
In 7d12e780e003f93433d49ce78cfedf4b4c52adc5 David Howells performed
this evolution:
"IRQ: Maintain regs pointer globally rather than passing to IRQ handlers"
He correctly updated many of the function definitions that were using this
extra regs pointer parameter but forgot to update some caller sites of
those functions. The reason the modifications was not properly done on all
drivers is that some drivers were rarely compiled because they are for
AMIGA, or that some code sites were inside #ifdefs where the option is not
set or inside #if 0.
Here is the semantic patch that found the occurences
and fixed the problem.
