Hi,
I noticed that after commit 212a871a393 (HID: hidraw: correctly deallocate
memory on device disconnect) hidraw doesn't close the underlying hid device
when the device node is closed last time.
For example I have a touch panel (HID over I2C) device with added debug
prints in i2c_hid_open()/i2c_hid_close():
# od -x /dev/hidraw0
[ 41.363813] i2c_hid 1-004c: i2c_hid_power lvl:32
[ 41.368464] i2c_hid 1-004c: i2c_hid_set_power
[ 41.372831] i2c_hid 1-004c: __i2c_hid_command: cmd=54 01 00 08
[ 41.451455] i2c_hid 1-004c: i2c_hid_open
^C
# od -x /dev/hidraw0
[ 58.420928] i2c_hid 1-004c: i2c_hid_power lvl:32
[ 58.425577] i2c_hid 1-004c: i2c_hid_set_power
[ 58.429945] i2c_hid 1-004c: __i2c_hid_command: cmd=54 01 00 08
[ 58.525276] i2c_hid 1-004c: i2c_hid_open
^C
i2c_hid_close() is never called. Is this intended or am I missing
something?
Thanks.
