Arnd Bergmann 702143d1de optee: simplify i2c access
[ Upstream commit 67bc809752 ]

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.
