HID: amd_sfh: Avoid disabling the interrupt
HP ProBook x360 435 G7 using older version of firmware which doesn't support disabling the interrupt for all commands. Hence avoid disabling the interrupt for that particular model. Link: https://bugzilla.kernel.org/show_bug.cgi?id=218104 Fixes: b300667b33b2 ("HID: amd_sfh: Disable the interrupt for all command") Co-developed-by: Akshata MukundShetty <akshata.mukundshetty@amd.com> Signed-off-by: Akshata MukundShetty <akshata.mukundshetty@amd.com> Signed-off-by: Basavaraj Natikar <Basavaraj.Natikar@amd.com> Signed-off-by: Jiri Kosina <jkosina@suse.com>
