From b35530650fcd9a61dfc57846d777f5cd77cd4abc Mon Sep 17 00:00:00 2001 From: Alan Cox Date: Wed, 12 Apr 2017 19:21:05 +0100 Subject: [PATCH] atomisp: remove most of the uses of atomisp_kernel_malloc They can be replaced by kmalloc. There are a few that do need to pick kmalloc or vmalloc. Those we leave for the moment.
