[PATCH v2 14/16] net: stmmac: remove dead code in stmmac_tx_clean

From: Corentin Labbe
Date: Wed Feb 08 2017 - 03:34:48 EST


Since commit cf32deec16e4 ("stmmac: add tx_skbuff_dma to save descriptors used by PTP"),
the struct dma_desc *p in stmmac_tx_clean was not used at all.

This patch remove this dead code.
