From: Adam Ford <aford173@gmail.com> mainline inclusion from mainline-5.10.62 commit 9a6a5602c2176b5ff68c9075f2c7b2aabe0d59b8 bugzilla: 182217 https://gitee.com/openeuler/kernel/issues/I4EFOS Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?i... -------------------------------- [ 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'.
