Sparse reports thise issue
ptdma-dmaengine.c:262:1: warning: symbol 'pt_tx_status' was not declared. Should it be static?
pt_tx_status, like other pt_* functions in ptdam-dmaengine.c, is assigned
to a function pointer and is not used directly outside of this file.
So change its storage-class specifier to static.
