Here's a collection of clk driver fixes.
- Fix qcom mux logic to look at the proper parent table member. Luckily this clk type isn't very common. - Don't kill clks on qcom systems that use Trion PLLs that are enabled out of the bootloader. We will simply skip programming the PLL rate if it's already done. - Use the proper clk_ops for the qcom sm6125 ICE clks. - Use module_platform_driver() in i.MX as it can be a module. - Fix a UAF in the versatile clk driver on an error path. -----BEGIN PGP SIGNATURE----- iQJFBAABCAAvFiEE9L57QeeUxqYDyoaDrQKIl8bklSUFAmG0DHkRHHNib3lkQGtl cm5lbC5vcmcACgkQrQKIl8bklSU2sA//RL+NpO52Vc5t42me5d9A00VP17Q+XUP/ 8MKuU6MoLNwPQ5R0QCTGzjrr9CnvzvyrIDBkqct9oZ68Cw+MUgH/GABJqMMj4Shk fyXFzHkEbu5Mifdw3z8iaszPWnHo0YkCFbUx3eyEHPeeZrFsh92P4B1pHdS5jEJ1 11zVczTXS06CWETGPgtmkPMNoMZSxVuGhfNSYfArdiKHCYrLctFxE2m9nF5tfIrL F6bBfTOJdBZOyViS487Jpn8tgrwFfH3gdcT95S5CEtKIKH2g8CRtjwldrlYsy3xt LUtaQUTuvpOTGEkcwxSIiqmlVkyiF/W8sKbYLc0NdVa2L3Aw4wE3OvlYLg0O4w2N I0Y7wAldxBl+Z8vlMgN2G6ZiZ8pSfRQkp0IY8IikkaPwiH0Dgb1elU45KclEsBzu SG4CGDv70Aft0ntxU5pwTZ9GDDRsWhHtkrxwRX+PKNtxf7zC+3n9fu/XoOW8WpAh zL0LRdXODwaxh32imM1AIqHWhMfkNWVobJuFMchV4VQ+y2x3jd8mE4ZirKSRc2M8 XF+iWCmqFIxviCWUD0k2NHtYuX9RiPrUCu19745A0msmih3riw6p14u6bYb5fKQT zWtJG5vue1ZbPjR14lPSgeK1tHwmw/z4gnosKVvNdiFPi1qppPZd+Bp7vZ5YZ5/N 2UmnUJ5eeMI= =qhVy -----END PGP SIGNATURE----- Merge tag 'clk-fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux Pull clk driver fixes from Stephen Boyd: - Fix qcom mux logic to look at the proper parent table member.
