2014-10-20staging: nvec: drop owner assignment from platform_driversWolfram Sang
A platform_driver does not need to set an owner, it will be populated by the driver core. Signed-off-by: Wolfram Sang <wsa@the-dreams.de>
2014-07-09staging: nvec: insert blank lines after declarationsPawel Lebioda
This patch fixes coding style warnings reported by checkpatch.pl: "Missing a blank line after declarations". Signed-off-by: Pawel Lebioda <pawel.lebioda89@gmail.com> Acked-by: Marc Dietrich <marvin24@gmx.de> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2014-03-07staging:nvec: Introduce the use of the managed version of kzallocHimangi Saraogi
This patch moves shared private data kzalloc to managed devm_kzalloc. There are no kfree statements associated with this data, so using devm adds the possibility of the data being freed, if the proble function fails (if that is possible) or if the remove function succeeds.
