[PATCH 05/20] ASoC: sti: uniperif_player: Fix clock leak in uni_player_init()

[Wentao Liang]

In uni_player_init(), player->clk is acquired via of_clk_get(). If any
subsequent operation fails (e.g. regmap_field_write(), devm_request_irq()),
or upon driver detachment, the acquired clock is never freed with
clk_put(), resulting in a resource leak.

Switch to devm_clk_get() so the clock is managed automatically and
properly released.
