[PATCH AUTOSEL 4.9 21/48] ARM: OMAP2+: Fix memleak in omap2xxx_clkt_vps_init

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Youling Tang <tangyouling@xxxxxxxxxxx>

[ Upstream commit 3c5902d270edb6ccc3049acfe5d3e96653c87dcd ]

If the clk_register fails, we should free hw before function returns to
prevent memleak.
