2020-09-22usb: appledisplay: use module_usb_driver to simplify the codeLiu Shixin1-13/+1
module_usb_driver() makes the code simpler by eliminating boilerplate code. Signed-off-by: Liu Shixin <liushixin2@huawei.com> Link: https://lore.kernel.org/r/20200918031012.3980558-1-liushixin2@huawei.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2020-09-16USB: legousbtower: use usb_control_msg_recv()Greg Kroah-Hartman1-41/+19
The usb_control_msg_recv() function can handle data on the stack, as well as properly detecting short reads, so move to use that function instead of the older usb_control_msg() call. This ends up removing a lot of extra lines in the driver.

2020-09-04usb/misc: usb3503: Use pm_ptr() macroPaul Cercueil1-10/+8
Use the newly introduced pm_ptr() macro, and mark the suspend/resume functions __maybe_unused. These functions can then be moved outside the CONFIG_PM_SUSPEND block, and the compiler can then process them and detect build failures independently of the config. If unused, they will simply be discarded by the compiler.

2020-07-21USB: Replace HTTP links with HTTPS onesAlexander A. Klimov1-2/+2
Rationale: Reduces attack surface on kernel devs opening the links for MITM as HTTPS traffic is much harder to manipulate. Deterministic algorithm: For each file: If not .svg: For each line: If doesn't contain `\bxmlns\b`: For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`: If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`: If both the HTTP and HTTPS versions return 200 OK and serve the same content: Replace HTTP with HTTPS.

2020-07-15usb: misc: sisusbvga: Move static const tables out to different include fileLee Jones3-631/+689
sisusb_init.h is included by multiple source files, but the big data tables contained are only referenced by one of them, leaving the tables 'defined but not used' by the remainder. We have a choice to either place them inside the source file, taking up may lines and potentially overwhelming the source file OR tuck them away neatly inside their own headerfile. The latter was chosen.

Apart from the cleanup, 1) the enum allows for better type checking, and 2) this saves some code. No more fiddling with bits is needed in assembly now. (OTOH, the structure is larger.)

For some reason, the TEST_ defines in the usb/ch9.h files did not have the USB_ prefix on it, making it a bit confusing when reading the file, as well as not the nicest thing to do in a uapi file. So fix that up and add the USB_ prefix on to them, and fix up all in-kernel usages. This included deleting the duplicate copy in the net2272.h file.

Commit 4d7201cda226 ("usb: usb251xb: add vdd supply support") didn't covered the non-DT use-case and so the regualtor_enable() call during probe will fail on those platforms. Also the commit didn't handled the error case correctly. Move devm_regulator_get() out of usb251xb_get_ofdata() to address the 1st issue. This can be done without worries because devm_regulator_get() handles the non-DT use-case too. Add devm_add_action_or_reset() to address the 2nd bug.

2020-02-12USB: misc: iowarrior: add support for the 28 and 28L devicesGreg Kroah-Hartman1-2/+13
Add new device ids for the 28 and 28L devices. These have 4 interfaces instead of 2, but the driver binds the same, so the driver changes are minimal.

Add support for two OEM devices that are identical to existing IO-Warrior devices, except for the USB device id.

2019-12-30usb: usb3503: Convert to use GPIO descriptorsLinus Walleij1-59/+35
This converts the USB3503 to pick GPIO descriptors from the device tree instead of iteratively picking out GPIO number references and then referencing these from the global GPIO numberspace. The USB3503 is only used from device tree among the in-tree platforms. If board files would still desire to use it they can provide machine descriptor tables. Make sure to preserve semantics such as the reset delay introduced by Stefan.

2019-12-10USB: adutux: fix interface sanity checkJohan Hovold1-1/+1
Make sure to use the current alternate setting when verifying the interface descriptors to avoid binding to an invalid interface. Failing to do so could cause the driver to misbehave or trigger a WARN() in usb_submit_urb() that kernels with panic_on_warn set would choke on.
