The stm32 nvmem driver fails to link as built-in when OPTEE is a loadable module: aarch64-linux-ld: drivers/nvmem/stm32-bsec-optee-ta.o: in function `stm32_bsec: stm32-bsec-optee-ta.c:(.text+0xc8): undefined reference to `tee_client_open_session' aarch64-linux-ld: drivers/nvmem/stm32-bsec-optee-ta.o: in function `stm32_bsec: stm32-bsec-optee-ta.c:(.text+0x1fc): undefined reference to `tee_client_open_context' Change the CONFIG_NVMEM_STM32_ROMEM definition so it can only be built-in if OPTEE is either built-in or disabled, and make NVMEM_STM32_BSEC_OPTEE_TA a hidden symbol instead.

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.
