Kees Cook b53b831919 dmaengine: stm32-dma3: Set lli_size after allocation ... With the new __counted_by annotation, the "lli_size" variable needs to valid for accesses to the "lli" array. This requirement is not met in stm32_dma3_chan_desc_alloc(), since "lli_size" starts at "0", so "lli" index "0" will not be considered valid during the initialization for loop. Fix this by setting lli_size immediately after allocation (similar to how this is handled in stm32_mdma_alloc_desc() for the node/count relationship).
