* fs: automount: Make automountpoints persistentSascha Hauer2016-01-081-3/+4

* cdev: When creating a new cdev, initialize device_nodeTrent Piepho2016-01-081-1/+4
| | | | | | | | | | | | | | | If a new cdev doesn't have a device_node defined when passed to devfs_create(), set it to the device_node of the parent device, if one exists. For non-partitions, like ocotp or eeprom devices, this is the correct thing to do. Partitions need to use, and do use, a different node. The code from commit 274e0b8dc48956babeaa2faf70bf8066e656b621 to set device_node in ocotp can be removed.

* fs: smhfs: Fix return value of truncate()Andrey Smirnov2015-11-091-1/+1
| | | | | | | | | | | | | | | Returning -ENOSYS as a result of truncate() breaks ability to write to semihosting host's filesystem, so change the return value to 0. This shouldn't cause any problems since all of the funcionlaity of truncate() should is already handled by 'open' (via O_TRUNC) and 'write' (will automatically grow the file size when writing) automatically Unfortunately this was missed in original commit that introduced semihosting Signed-off-by: Andrey Smirnov <andrew.smirnov@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| * fs: pass path directly to cdev_openSascha Hauer2015-10-151-6/+1

* | introduce strerrorpSascha Hauer2015-09-231-1/+1
|/ | | | | | | | | | putting an error pointer into strerror can be a bit confusing since strerror takes a positive error code but PTR_ERR returns a negative number, so we have to do strerror(-PTR_ERR(errp)). Some places got this wrong already, so introduce a strerrorp function which directly takes an error pointer. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* cdev: Add function to find cdev by device_nodeSascha Hauer2015-09-011-0/+13
| | | | | | | | | | This adds a device_node member to struct cdev and a function to find a cdev by device_node. This also removes the setting of cdev->dev->device_node in the of partition parser. We must not set the device since it may not refer to a partition but to a whole device with partitions. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
