From 0ffa0285052607513a29f529ddb5061c907fd8a6 Mon Sep 17 00:00:00 2001 From: Hans-Peter Nilsson Date: Mon, 12 Feb 2007 00:52:45 -0800 Subject: [PATCH] SPI cleanup() method param becomes non-const I'd like to assign NULL to kfree()d members of a structure. I can't do that without ugly casting (see the PXA patch) when the structure pointed to is const-qualified. I don't really see a reason why the cleanup method isn't allowed to alter the object it should clean up. :-) No, I didn't test the PXA patch, but I verified that the NULL-assignment doesn't stop me from doing rmmod/insmodding my own spi_bitbang-based driver.
