Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/hid/hid
Pull HID fixes from Jiri Kosina: - revert of the high-resolution scrolling feature, as it breaks certain hardware due to incompatibilities between Logitech and Microsoft worlds. Peter Hutterer is working on a fixed implementation. Until that is finished, revert by Benjamin Tissoires. - revert of incorrect strncpy->strlcpy conversion in uhid, from David Herrmann - fix for buggy sendfile() implementation on uhid device node, from Eric Biggers - a few assorted device-ID specific quirks * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/hid/hid: Revert "Input: Add the `REL_WHEEL_HI_RES` event code" Revert "HID: input: Create a utility class for counting scroll events" Revert "HID: logitech: Add function to enable HID++ 1.0 "scrolling acceleration"" Revert "HID: logitech: Enable high-resolution scrolling on Logitech mice" Revert "HID: logitech: Use LDJ_DEVICE macro for existing Logitech mice" Revert "HID: logitech: fix a used uninitialized GCC warning" Revert "HID: input: simplify/fix high-res scroll event handling" HID: Add quirk for Primax PIXART OEM mice HID: i2c-hid: Disable runtime PM for LG touchscreen HID: multitouch: Add pointstick support for Cirque Touchpad HID: steam: remove input device when a hid client is running. Revert "HID: uhid: use strlcpy() instead of strncpy()" HID: uhid: forbid UHID_CREATE under KERNEL_DS or elevated privileges HID: input: Ignore battery reported by Symbol DS4308 HID: Add quirk for Microsoft PIXART OEM mouse

@ -190,16 +190,7 @@ A few EV_REL codes have special meanings:
|
|||
* REL_WHEEL, REL_HWHEEL:
|
||||
|
||||
- These codes are used for vertical and horizontal scroll wheels,
|
||||
respectively. The value is the number of "notches" moved on the wheel, the
|
||||
physical size of which varies by device. For high-resolution wheels (which
|
||||
report multiple events for each notch of movement, or do not have notches)
|
||||
this may be an approximation based on the high-resolution scroll events.
|
||||
|
||||
* REL_WHEEL_HI_RES:
|
||||
|
||||
- If a vertical scroll wheel supports high-resolution scrolling, this code
|
||||
will be emitted in addition to REL_WHEEL. The value is the (approximate)
|
||||
distance travelled by the user's finger, in microns.
|
||||
respectively.
