Writing to the built-in strings arrays doesn't work if driver is loaded as kernel module. This is also considered as a bad pattern. Fix this by adding a call to clk_get() with legacy clock name. This fixes following kernel oops if driver is loaded as module: Unable to handle kernel paging request at virtual address bf047978 pgd = (ptrval) [bf047978] *pgd=59344811, *pte=5903c6df, *ppte=5903c65f Internal error: Oops: 80f [#1] SMP ARM Modules linked in: mc exynosdrm(+) analogix_dp rtc_s3c exynos_ppmu i2c_gpio CPU: 1 PID: 212 Comm: systemd-udevd Not tainted 5.6.0-rc2-next-20200219 #326 videodev: Linux video capture interface: v2.00 Hardware name: Samsung Exynos (Flattened Device Tree) PC is at exynos_dsi_probe+0x1f0/0x384 [exynosdrm] LR is at exynos_dsi_probe+0x1dc/0x384 [exynosdrm] ...

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
