HID: i2c-hid: Fix "(null)" output when reading report descriptor fails
When i2c-hid fails to read the HID report descriptor during device initialization, the error message prints as: hid (null): reading report descriptor failed The HID device name is set in hid_add_device() after calling hdev->ll_driver->parse(), so when i2c_hid_parse() fails and calls hid_err(), the device name has not been set yet, resulting in "(null)" output. Use dev_err(&client->dev, ...) instead of hid_err(hid, ...) because the I2C client device is fully initialized with a proper name, providing meaningful error messages for debugging. Before: hid (null): reading report descriptor failed After: i2c_hid i2c-TPD0001:00: reading report descriptor failed Fixes: 4a200c3b9a40 ("HID: i2c-hid: introduce HID over i2c specification implementation") Signed-off-by: Ai Chao <aichao@kylinos.cn> Reviewed-by: Mario Limonciello (AMD) <superm1@kernel.org> Signed-off-by: Jiri Kosina <jkosina@suse.com>
