Revision 2cff98b99c469880ce830cbcde015b53b67e0a7b authored by Dean Nelson on 29 April 2015, 15:09:18 UTC, committed by Will Deacon on 29 April 2015, 16:39:39 UTC
__dma_alloc() does a PAGE_ALIGN() on the passed in size argument before doing anything else. __dma_free() does not. And because it doesn't, it is possible to leak memory should size not be an integer multiple of PAGE_SIZE. The solution is to add a PAGE_ALIGN() to __dma_free() like is done in __dma_alloc(). Additionally, this patch removes a redundant PAGE_ALIGN() from __dma_alloc_coherent(), since __dma_alloc_coherent() can only be called from __dma_alloc(), which already does a PAGE_ALIGN() before the call.
