Fix the following compilation warnings :
../arch/arm/mach-stm32mp/stm32mp1/spl.c: In function 'stm32_init_tzc_for_optee': ../arch/arm/mach-stm32mp/stm32mp1/spl.c:148:37: warning: 'optee_size' may be used uninitialized [-Wmaybe-uninitialized] 148 | tee_shmem_base = optee_base + optee_size - CFG_SHMEM_SIZE; | ~~~~~~~~~~~^~~~~~~~~~~~ ../arch/arm/mach-stm32mp/stm32mp1/spl.c:137:30: note: 'optee_size' was declared here 137 | uint32_t optee_base, optee_size, tee_shmem_base; | ^~~~~~~~~~ ../arch/arm/mach-stm32mp/stm32mp1/spl.c:148:37: warning: 'optee_base' may be used uninitialized [-Wmaybe-uninitialized] 148 | tee_shmem_base = optee_base + optee_size - CFG_SHMEM_SIZE; | ~~~~~~~~~~~^~~~~~~~~~~~ ../arch/arm/mach-stm32mp/stm32mp1/spl.c:137:18: note: 'optee_base' was declared here 137 | uint32_t optee_base, optee_size, tee_shmem_base; | ^~~~~~~~~~
Fix also the following checkpatch "check" :
CHECK: Prefer kernel type 'u32' over 'uint32_t' 37: FILE: arch/arm/mach-stm32mp/stm32mp1/spl.c:137: + uint32_t optee_base = 0, optee_size = 0, tee_shmem_base;
