Storing a bogus i2c_client structure on the stack adds overhead and causes a compile-time warning:
drivers/tee/optee/rpc.c:493:6: error: stack frame size of 1056 bytes in function 'optee_handle_rpc' [-Werror,-Wframe-larger-than=] void optee_handle_rpc(struct tee_context *ctx, struct optee_rpc_param *param,
Change the implementation of handle_rpc_func_cmd_i2c_transfer() to open-code the i2c_transfer() call, which makes it easier to read and avoids the warning.
Fixes: c05210ab9757 ("drivers: optee: allow op-tee to access devices on the i2c bus")
does fixing stack-frame compile warnings need a 'fixes' tag?
The fixes tag only describes which commit introduced the bug, it is irrelevant what type of bug this is.
