✨ scmi_common_...max_msg_size(9) ✨

okay so bestie, welcome to the Kernel API Manual 💖 — this is the page for scmi_common_get_max_msg_size, and yes the title got cutely truncated with ... because kernel function names are apparently allergic to being short. iykyk 💅

int scmi_common_get_max_msg_size (const struct scmi_protocol_handle *ph
);

no cap, that's the whole signature. one arg, one int coming back atcha ✨

💜 ARGUMENTS 💜

• ph — a protocol handle reference, bestie. that's your ticket to the protocol party 🎟️
