2018-07-18USB: serial: cp210x: make line-speed quantisation data drivenJohan Hovold1-43/+56
Older cp210x devices only support a fixed set of line speeds to which a requested speed is mapped. Reimplement this mapping using a table instead of a long if-else construct. Reviewed-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Signed-off-by: Johan Hovold <johan@kernel.org>

2018-07-11USB: serial: kl5kusb105: remove KLSI device idJohan Hovold2-4/+0
This driver was apparently never tested with an actual KLSI device. In fact, even the device-id entry which was supposed to allow for this had a typo in it. Tests now reveal that the predicted firmware differences with the PalmConnect adapters are real and that the driver does not support KLSI devices with PID 0x000c, so let's remove the broken entry.

2018-06-13treewide: kmalloc() -> kmalloc_array()Kees Cook1-2/+2
The kmalloc() function has a 2-factor argument form, kmalloc_array(). This patch replaces cases of: kmalloc(a * b, gfp) with: kmalloc_array(a * b, gfp) as well as handling cases of: kmalloc(a * b * c, gfp) with: kmalloc(array3_size(a, b, c), gfp) as it's slightly less ugly than: kmalloc_array(array_size(a, b), c, gfp) This does, however, attempt to ignore constant size factors like: kmalloc(4 * 1024, gfp) though any constants defined via macros get caught up in the conversion. Any factors with a sizeof() of "unsigned char", "char", and "u8" were dropped, since they're redundant. The tools/ directory was manually excluded, since it has its own implementation of kmalloc(). The Coccinelle script used for this was: // Fix redundant parens around sizeof(). @@ type TYPE; expression THING, E; @@ ( kmalloc( - (sizeof(TYPE)) * E + sizeof(TYPE) * E , ...) | kmalloc( - (sizeof(THING)) * E + sizeof(THING) * E , ...) ) // Drop single-byte sizes and redundant parens. @@ expression COUNT;

2018-05-02USB: serial: visor: handle potential invalid device configurationGreg Kroah-Hartman1-34/+35
If we get an invalid device configuration from a palm 3 type device, we might incorrectly parse things, and we have the potential to crash in "interesting" ways. Fix this up by verifying the size of the configuration passed to us by the device, and only if it is correct, will we handle it. Note that this also fixes an information leak of slab data.

2018-04-16USB: serial: ftdi_sio: use jtag quirk for Arrow USB BlasterVasyl Vavrychuk1-1/+2
Arrow USB Blaster integrated on MAX1000 board uses the same vendor ID (0x0403) and product ID (0x6010) as the "original" FTDI device. This patch avoids picking up by ftdi_sio of the first interface of this USB device. After that this device can be used by Arrow user-space JTAG driver.
