The spec states that the HID devices should allow the host to query the HID descriptor at any time. Some devices require the HID descriptor to be set on resume, or they will fail. Instead of having a growing list of blacklisted devices make the call part of the general resume process so we can remove this list. Tested on a Dell XPS 9360 and a Surface 3. link: https://bugzilla.redhat.com/show_bug.cgi?id=1622695 Signed-off-by: Benjamin Tissoires <redacted> --- drivers/hid/i2c-hid/i2c-hid.c | 16 ++++------------ 1 file changed, 4 insertions(+), 12 deletions(-)
