| Subject: [PATCH] nvmem: stm32: fix OPTEE dependency
 | |
| 
 | |
| 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.
