* [PATCH 2/2] fs: remove unnecessary device pointer argument
  2015-03-04  7:49 [PATCH 1/2] fs: rename inode member of struct filep to priv Sascha Hauer

  0 siblings, 1 reply; 6+ messages in thread
From: Sascha Hauer @ 2015-03-04  7:49 UTC (permalink / raw)
  To: Barebox List

The struct device_d * argument is not necessary, it can be retrieved from
the FILE *. This adds a convenience function for doing this and removes
the struct device_d * argument from the the filesystem drivers functions.
