Subject: [PATCH 199/201] util: use only /dev directory in open_dev()
|
||
|
|
|
||
|
|
Previously, open_dev() tried to open device in two ways - using /dev and
|
||
|
|
/tmp directory. This method could be used by users which have no access
|
||
|
|
to /tmp directory (e.g. udev) and dev_open() fails which may affect many
|
||
|
|
processes. Remove try to open in /tmp directory.
