From: Ian Abbott Date: Thu, 1 Nov 2012 16:28:30 +0000 (+0000) Subject: staging: comedi: gsc_hpdi: remove board(dev) function X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=6526cd1ad04adc2ca54d34d1f003b8bb5318d337;p=linux-beck.git staging: comedi: gsc_hpdi: remove board(dev) function The `board(dev)` function just casts `dev->board_ptr` to a pointer to the private data type `struct hpdi_private` and returns it. It's only called from one function: `hpdi_auto_attach()`. Remove `board()` and use a local variable to point to the `struct hpdi_private` data structure.
