Kulikov Vasiliy b9033e682e dma: dmatest: fix potential sign bug ... 'cnt' is unsigned, so this code may become wrong in future as dmatest_add_threads() can return error code: cnt = dmatest_add_threads(dtc, DMA_MEMCPY); thread_count += cnt > 0 ? cnt : 0; ^^^^^^^ Now it can return only -EINVAL if and only if second argument of dmatest_add_threads() is not one of DMA_MEMCPY, DMA_XOR, DMA_PQ. So, now it is not wrong but may become wrong in future. The semantic patch that finds this problem (many false-positive results): (http://coccinelle.lip6.fr/) // <smpl> @ r1 @ identifier f; @@ int f(...) { ... } @@ identifier r1.f; type T; unsigned T x; @@ *x = f(...) ... *x > 0 Signed-off-by: Kulikov Vasiliy <segooon@gmail.com> Signed-off-by: Dan Williams <dan.j.williams@intel.com>		2010-08-04 14:27:47 -07:00
