Subject: [PATCH net] dpll: zl3073x: fix memory leak on pin registration failure
Date: Fri, 15 May 2026 21:39:56 +0200 [thread overview]
Message-ID: <20260515193956.351092-1-ivecera@redhat.com> (raw)
If zl3073x_dpll_pin_register() fails, the allocated pin is not yet
added to zldpll->pins list. The error path calls
zl3073x_dpll_pins_unregister() which only iterates pins on the list,
so the current pin is leaked. Free the pin before jumping to the error
label.
Fixes: 75a71ecc2412 ("dpll: zl3073x: Register DPLL devices and pins")
