Subject: [PATCH 5.10 053/103] clk: renesas: rcar-usb2-clock-sel: Fix kernel NULL pointer dereference

From: Adam Ford <aford173@...il.com>

[ Upstream commit 1669a941f7c4844ae808cf441db51dde9e94db07 ]

The probe was manually passing NULL instead of dev to devm_clk_hw_register.
This caused a Unable to handle kernel NULL pointer dereference error.
Fix this by passing 'dev'.
