🛟 Devin Lifeguard found 4 likely issues in this PR

• use-typedefs-not-stdint snippet: Replace the newly added uint32_t declarations (e.g. uint32_t volatile g_tx_complete = 0;) with the project typedef word32 (e.g. volatile word32 g_tx_complete = 0;) and similarly update other new instances of uint32_t introduced in this commit.
• check-all-return-codes snippet snippet: Add error-handling after the calls, e.g. if (err != FSP_SUCCESS) { /* handle error */ } after R_SCI_UART_Open and check the return of R_SCI_UART_Write, propagating or logging failures as appropriate.
• no-memory-leaks snippet: In wc_CryptoCb_CleanupRenesasCmn() first obtain cbInfo (e.g. cbInfo = (FSPSM_ST*)gCbCtx[*id - INITIAL_DEVID];) and then free when it is not NULL (if (cbInfo && cbInfo->internal) { XFREE(cbInfo->internal, cbInfo->internal->heap, DYNAMIC_TYPE_TMP_BUFFER); cbInfo->internal = NULL; }), removing the inverted check and the premature dereference.
• pointer-null-check snippet: Assign cbInfo before dereferencing and add a NULL check, e.g. FSPSM_ST* cbInfo = gCbCtx[*id - INITIAL_DEVID]; if (cbInfo != NULL && cbInfo->internal != NULL) { ... }.

• [nitpick] Adding the ssl NULL check is good defensive programming, but consider checking ssl before user_ctx since ssl is used in the error message context. The order of checks should follow the order of usage.

• Parameter name inconsistency: the parameter was renamed from 'cipher_lengh' to 'cipher_length' (fixing the typo), but on line 247 it's still referenced as 'cipher_lengh'. Ensure all parameter names are consistent.
