From 22e05b4549bf2405d6aca128540b20cd2dd33f1f Mon Sep 17 00:00:00 2001 From: Sergei Shtylylov Date: Sun, 5 Oct 2008 18:23:27 +0200 Subject: [PATCH] ide-dma: fix ide_build_dmatable() for TRM290 Apparently, 'xcount' being 0 does not mean 0 bytes for TRM290; it means 4 bytes, judging from the code immediately preceding this check. So, we must never try to "split" the PRD for TRM290. This is probably never hit anyway -- with the DMA buffers aligned to at least 512 bytes and ATAPI DMA not being used for non block I/O commands...
