USB: Simplify USB ID table match

2020-07-29T14:48:02+00:00

usb_device_match_id() supports being passed NULL tables, so no need to
check for it.

usb: usbfs: stop using compat_alloc_user_space

2020-07-22T11:13:22+00:00

Just switch the low-level routines to take kernel structures, and do the
conversion from the compat to the native structure on that.

usb: core: fix quirks_param_set() writing to a const pointer

2020-07-21T11:38:21+00:00

The function quirks_param_set() takes as argument a const char* pointer
to the new value of the usbcore.quirks parameter. It then casts this
pointer to a non-const char* pointer and passes it to the strsep()
function, which overwrites the value.

Fix this by creating a copy of the value using kstrdup() and letting
that copy be written to by strsep().

usb: hcd: Try MSI interrupts on PCI devices

2020-07-21T11:38:21+00:00

It appears that some platforms share same IRQ line between several devices,
some of which are EHCI and OHCI controllers. This is neither practical nor
performance-wise, especially in the case when they are supporting MSI.

In order to improve the situation try to allocate MSI and fallback to legacy
IRQ if no MSI available.

usb: Use fallthrough pseudo-keyword

2020-07-10T06:55:17+00:00

Replace the existing /* fall through */ comments and its variants with
the new pseudo-keyword macro fallthrough[1]. Also, remove unnecessary
fall-through markings when it is the case.

USB: Fix up terminology

2020-07-01T12:04:04+00:00

USB is a HOST/DEVICE protocol, as per the specification and all
documentation.  Fix up terms that are not applicable to make things
match up with the terms used through the rest of the USB stack.

USB: OTG: rename product list of devices

2020-06-19T06:58:55+00:00

Rename the list of specific devices that an OTG device could support to
make it more obvious as to what this list is for and what it is doing.
Also rename the configuration option to make it more obvious as well.

USB: rename USB OTG hub configuration option

The USB OTG code has the ability to disable external hubs, but the
configuration option for it is oddly named.  Rename it to be more
obvious as to what it does.
