From c35205aa051244a5ee8ed1e124b9c7b890d97ad9 Mon Sep 17 00:00:00 2001 From: Matthijs Kooijman Date: Fri, 30 Aug 2013 18:45:18 +0200 Subject: [PATCH] staging: dwc2: re-use hptxfsiz variable For some reason, the value of the HPTXFSIZ register was built in the ptxfsiz variable, while there was also a hptxfsiz variable availble. Better just use that and remove the (now unused) ptxfsiz variable.
