Xuanqiang Luo says: ==================== net: phy: dp83640: fix shared clock lifetime and probe error cleanup The DP83640 driver shares one PTP clock between all PHYs on the same MII bus. Its driver-local clock lookup and removal scheme can leak the shared clock on probe failure or free it while another probe is acquiring it. This series moves the shared clock to the PHY package infrastructure. Patch 1 adds PHY package locking helpers. Patch 2 embeds the pin configuration in the shared clock. Patch 3 clears per-PHY state when PTP clock registration fails. Patch 4 fixes the shared clock lifetime using the PHY package infrastructure. ==================== Link: https://patch.msgid.link/20260811151345.73582-1-xuanqiang.luo@linux.dev Signed-off-by: Jakub Kicinski <kuba@kernel.org>
Linux kernel ============ The Linux kernel is the core of any Linux operating system. It manages hardware, system resources, and provides the fundamental services for all other software.
