4.16-stable review patch. If anyone has any objections, please let me know.

commit b658912cb023cd6f8e46963d29779903d3c10538 upstream.
i2c_hid_command() returns non-zero in error cases (the actual errno). Error handling in for I2C_HID_QUIRK_RESEND_REPORT_DESCR case in i2c_hid_resume() had the check inverted; fix that.
