If device_add() is called with a device which does not have dev->p set up, then device_private_init() is called. If that succeeds, then the error variable is set to 0. Now if the dev_name(dev) check further down fails, then device_add() correctly terminates, but returns 0. That of course lets the driver progress. If later another driver uses this half set up device as parent then device_add() of the child device explodes and renders sysfs completely unusable. Set the error to -EINVAL if dev_name() check fails. Signed-off-by:

Most device_attributes are const, and are begging to be put in a ro section. However, the create and remove file interfaces were failing to propagate the const promise which the only functions they call offer. Signed-off-by:

- it is possible to submit patches for the stable queue without sending them directly stable@kernel.org. If the tag (Cc: stable@kernel.org) is available in the sign-off area than hpa's script will filter them into the stable mailbox once it hits Linus' tree. - Patches which require others to be applied first can be also specified.

Filesystem code usually destroys the option buffer while parsing it. This leads to errors when the same buffer is passed twice. In case we fill a new superblock do not call remount. This is needed to quite a warning that the debugfs code causes every boot. Cc: Miklos Szeredi <miklos@szeredi.hu> Signed-off-by:

devtmpfs has a rw_lock dirlock which serializes delete_path and create_path. This code was obviously never tested with the usual set of debugging facilities enabled. In the dirlock held sections the code calls: - vfs functions which take mutexes - kmalloc(, GFP_KERNEL) In both code pathes the might sleep warning triggers and spams dmesg. Convert the rw_lock to a mutex. There is no reason why this needs to be a rwlock. Signed-off-by:

The USB serial code was a new user of the kfifo API, and it was missed when porting things to the new kfifo API. Please make the write_fifo in place. Here is my patch to fix the regression and full ported version. Signed-off-by:

This fixes LVDS on some mac laptops without a panel edid. v2 - Set proper mode type flags v3 - Note that this is not neceesarily the exact panel mode, but an approximation based on the cvt formula. For these systems we should ideally read the mode info out of the registers or add a mode table, but this works and is much simpler. v4 - Update comments and debug message. Signed-off-by:
