💅 spi_nor_spimem_check_readop — Kernel API Manual ✨

okay bestie, settle in, because this one is literally a vibe check for a read operation 🌸 — we're looking at spi_nor_spimem_check_readop(9) from the Kernel API Manual, and no cap, it's short but it's important.

✨ NAME ✨

spi_nor_spimem_check_readop — checks whether this read op is actually supported by the controller 🫶

🎀 SYNOPSIS 🎀

int spi_nor_spimem_check_readop (struct spi_nor *nor , const struct
spi_nor_read_command *read );

like, that's the whole signature, and yes it returns an int 💖

💅 ARGUMENTS 💅

  • nor — pointer to a struct spi_nor 🦋 (your NOR flash boy, the main character)
  • read — pointer to the op template that's getting checked 👀 (this is the thing under review, the one on trial)

🔥 DESCRIPTION 🔥

Returns 0 if the operation is supported, and -EOPNOTSUPP otherwise 💀

that's it. that's the whole description. it's giving "small function, big responsibility" and honestly? iconic 👑

ngl the vibes here are very "yes or no, no in-between" — you get 0 (slay, supported) or -EOPNOTSUPP (nope, not supported). no other options, periodt 💅
