Remove the special handling for the Data TLB entry dirty bit in the TLB-miss handler. As the code stands, all that it does is to cause us to take a second data address exception to set the dirty bit. Instead, we can just let pte_mkdirty() set the bit. Signed-off-by:

In moxa.c there are 32 minor numbers reserved for each device. The number of ports actually available per device is stored in moxa_board_conf->numPorts. This number is not considered in moxa_open(). Opening a port that is not available results in a kernel oops. This patch adds a test to moxa_open() that prevents opening unavailable ports. Signed-off-by:

Fabian Godehardt authored
upper layers, namely line discipline, need to be notified when transmission of more data is possible. For spurious cases, where IRQ handling does not supply notification for sure, it is given additionally here, when data has just been transmitted and space in the buffer will most probably be available.

Daniel Glöckner authored
"have_rtscts" is assigned 1, while it is declared int:1, two's complement, which can hold 0 and -1 only. The code works, as the upper bits are cut off, and tests are done against 0 only. Nonetheless, correctly declaring the bit field as unsigned int:1 renders the code more robust. Signed-off-by:

Interface blacklisting is necessary for non-serial interfaces that are handled by a different driver. The interface blacklisting is implemented in sierra driver per device. Each device in need of a blacklist has a static information array kept in the driver. This array contains the interface numbers that are blacklisted. The pointer for each blacklist array and the length of that blacklist are 'bundled' in data structure sierra_iface_info. A pointer to this information is set in id_table when the device is added to the id_table. The following is summary of changes we have made to sierra.c driver in this patch dealing with interface blacklisting support: - Added data structure sierra_iface_info and function is_blacklisted() to support blacklisting - Modified sierra_probe() to handle blacklisted interfaces accordingly - Improved comments in id_table - Added new device in id_table with blacklist interface support Signed-off-by:

[Folded from eight patches into one as the original set according to the author "All of the patches need to be applied to obtain a working product" so keeping them split seems unhelpful Merge fixes done versus other conflicting changes and moved the spin_lock_init from open to setup time -- Alan] Summary of the changes and code re-organization in this patch: - The memory for urbs is allocated and urbs are submitted only for the active interfaces (instead of pre-allocating these for all interfaces). This will save memory especially in the case of using composite devices. - The code has been re-organized and functionality has been extracted from sierra_startup(), sierra_shutdown(), sierra_open(), sierra_close() and added in helper functions sierra_release_urb(), sierra_stop_rx_urbs(), sierra_submit_rx_urbs() and sierra_setup_urb() - Added function sierra_release_urb() to free an urb and its transfer buffer. - Removed unecessary include file reference and comment. - Added function sierra_stop_rx_urbs() that takes care of the release of receive and interrupt urbs. This function is to be called by sierra_close() whenever an interface is de-activated. - Added new function sierra_submit_rx_urbs() that handles the submission of receive urbs and interrupt urbs (if any) during the interface activation. This function is to be called by sierra_open(). Added a second parameter to pass the memory allocation (as suggested by Oliver Neukum) so that this function can be used in post_reset() and resume(). - Added new function sierra_setup_urb() that contains the functionality to allocate an urb, fill bulk urb using the supplied memory allocation flag and release urb upon error. Added parameter so that the caller pass the memory allocation flag for flexibility. - Moved sierra_close() before sierra_open() to resolve dependencies introduced by the code reorganization. - Modified sierra_close() to call sierra_stop_rx_urbs() and sierra_release_urb() functions added in previous patch. - Modified sierra_open() to call sierra_setup_urb() and sierra_submit_rx_urbs() functions; note urbs are allocated and submitted for each activated interface. - Modified sierra_startup() so that allocation of urbs happens whenever an interface is activated (urb allocation is moved to sierra_open()). - Modified sierra_shutdown() so that urbs are freed whenever an interface is de-activated (urb freeing moved to sierra_close() as shown in previous patch from the series) - Removed unecessary data structure from sierra_port_private_data - Suppress an entry in logs by not re-submitting an urb when usb_submit_urb() returns -EPERM, as this shows that usb_kill_urb() is running (as suggested by Oliver Neukum) Signed-off-by:

Bluetooth shouldn't be doing this as most drivers don't support the flag, furthermore it shouldn't be needed with newer buffering. This becomes rather more visible as the locking fixes make the abuse of low_latency visible as spew on the users console/dmesg. Signed-off-by:

Alan Cox authored
This allows users to use the standard setserial command with this FT232 feature as well as obscure chip specific interfaces we have now. We keep track of and respect the sysfs value for non-low-latency cases. In theory we could do smart stuff with VTIME and the like but this seems of questionable worth.

This patch replaces the string "CP2101" with "CP210x" within cp210x.c This is to reduce confusion about the fact that the driver is actually compatible with CP2101, CP2102 and CP2103 devices. Signed-off-by:

Craig Shelley authored
The CP210X driver was developed without official device specifications. This has lead to an incorrect assumption that all GET request codes are equal to the corresponding SET request code +1. This patch removes this incorrect assumption, and uses request code definitions based on the updated GPL driver from SiLabs. This modification is needed before extended functionality such as GPIO on CP2103 can be supported. Signed-off-by:
