[PATCH v2] clk: eyeq: fix memory leak in eqc_auxdev_create() error path

[Guangshuo Li]

eqc_auxdev_create() allocates an auxiliary_device with kzalloc() before
calling auxiliary_device_init().

When auxiliary_device_init() returns an error, the function exits
without freeing adev. Since the release callback is only expected to
handle cleanup after successful initialization, adev should be freed
explicitly in this path.

Add the missing kfree(adev) before returning from the
auxiliary_device_init() error path.
