From: H Hartley Sweeten Date: Wed, 9 Jan 2013 20:32:18 +0000 (-0700) Subject: staging: comedi: comedi_buf: don't expose comedi_buf_write_n_allocated() X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=8bd650f91be07fb84adc2e47fb1379b7223b95a4;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git staging: comedi: comedi_buf: don't expose comedi_buf_write_n_allocated() This helper function is only called by the comedi core in comedi_buf.c and comedi_fops.c. For aesthetic reasons, move it to comedi_buf.c and remove the inline. Move the prototype from comedidev.h to comedi_internal.h so it's not exposed outside the comedi core.
