[PATCH] can: at91_can: fix an error handle in at91_can_probe()
From: Haoxiang Li <hidden>
Date: 2026-01-25 12:15:43
Also in:
linux-can, lkml, stable
Subsystem:
can network drivers, the rest · Maintainers:
Marc Kleine-Budde, Vincent Mailhol, Linus Torvalds
In at91_can_probe(), if devm_phy_optional_get() fails,
the memory allocated by alloc_candev() should be freed.
Modify the goto label to do so.
