Subject: greybus: hid: Don't disable connection-tx before destroying hid-device
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=b22b7104d5930ed4aae2c8494b8f95f20a85d66b;p=linux-beck.git

greybus: hid: Don't disable connection-tx before destroying hid-device

hid_destroy_device() can potentially call callbacks defined in struct
hid_ll_driver, which may initiate few greybus operations.

And so connection (tx) should be kept enabled until the hid-device isn't
destroyed.
