Subject: [PATCH] clk: at91: fix count of periph clocks passed to pmc_data_allocate
Date: Wed, 9 Jun 2021 10:01:44 +0200 [thread overview]
Message-ID: <20210609080145.44226-1-clement.leger@bootlin.com> (raw)
When allocating clk_hw structure, only the periph32 clocks are considered.
Since sama5d2_periphck are also added to the phws there is currently an
out of bound write. Fix this by adding the count of periphck to periph32ck.
