Subject: [PATCH v1] HID: i2c-hid: use print_hex_dump_debug to print report descriptor
From: Riwen Lu <luriwen@...inos.cn>
The format '%*ph' print up to 64 bytes long as a hex string with ' '
sepatator. Usually the size of report descriptor is larger than 64
bytes, so consider using print_hex_dump_debug to print out all of it for
better debugging.
