Subject: [PATCH next] HID: i2c-hid: Fix test in i2c_hid_core_register_panel_follower()
Date: Wed, 27 Aug 2025 15:57:31 +0300	[thread overview]
Message-ID: <aK8Au3CgZSTvfEJ6@stanley.mountain> (raw)

Bitwise AND was intended instead of OR.  With the current code the
condition is always true.

Fixes: cbdd16b818ee ("HID: i2c-hid: Make elan touch controllers power on after panel is enabled")
Signed-off-by: Dan Carpenter <dan.carpenter@linaro.org>
