From: H Hartley Sweeten Date: Wed, 9 Jan 2013 20:31:46 +0000 (-0700) Subject: staging: comedi: comedi_buf: don't expose comedi_buf_read_n_allocated() X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=5b2b64b7510292f4b1e6363edb6f53c39828672e;p=linux-beck.git staging: comedi: comedi_buf: don't expose comedi_buf_read_n_allocated() This helper function is only called in comedi_buf.c. Move it there and make it static so it's not exposed globally.
