Thanks for the reply.

Since in my case there are a large no of instances. Automating the
non-nested ones like
drivers/rtc/rtc-rs5c372.c
106 struct i2c_msg msgs[] = {
107 { client->addr, I2C_M_RD, sizeof rs5c->buf, rs5c->buf },
108 };

Yes it is.
However the one with only one like the above is also there.
