Subject: [PATCH] clk: versatile: clk-icst: use after free on error path
Date: Wed, 17 Nov 2021 10:26:05 +0300	[thread overview]
Message-ID: <20211117072604.GC5237@kili> (raw)

This frees "name" and then tries to display in as part of the error
message on the next line.  Swap the order.

Fixes: 1b2189f3aa50 ("clk: versatile: clk-icst: Ensure clock names are unique")
