Merge tag 'clk-imx-6.9' of git://git.kernel.org/pub/scm/linux/kernel/git/abelvesa/linux into clk-imx

Pull i.MX clk driver updates from Abel Vesa:

 - Minor clean-ups and error handling improvements in both composite-8m
   and SCU clock drivers
 - Fix for SAI_MCLK_SEL definition for i.MX8MP

* tag 'clk-imx-6.9' of git://git.kernel.org/pub/scm/linux/kernel/git/abelvesa/linux:
  clk: imx: imx8mp: Fix SAI_MCLK_SEL definition
  clk: imx: scu: Use common error handling code in imx_clk_scu_alloc_dev()
  clk: imx: composite-8m: Delete two unnecessary initialisations in __imx8m_clk_hw_composite()
  clk: imx: composite-8m: Less function calls in __imx8m_clk_hw_composite() after error detection
