[3/5] clk: imx: imx8: Fix an error handling path in imx8_acm_clk_probe()

Commit Message

Christophe JAILLET Aug. 27, 2023, 9:37 a.m. UTC

If an error occurs after a successful clk_imx_acm_attach_pm_domains() call,
it must be undone.

Add an explicit error handling path, Re-order the code and add the missing
clk_imx_acm_detach_pm_domains() call.
