[PATCH] spi: stm32-qspi: fix debug format string

[Arnd Bergmann]

From: Arnd Bergmann <arnd@arndb.de>

Printing size_t needs a special %zd format modifier to avoid a
warning like:

drivers/spi/spi-stm32-qspi.c:481:41: note: format string is defined here
  481 |         dev_dbg(qspi->dev, "%s len = 0x%x offs = 0x%llx buf = 0x%p\n", __func__, len, offs, buf);

Fixes: 18674dee3cd6 ("spi: stm32-qspi: Add dirmap support")

This doesn't apply against current code, please check and resend.

It appears that you just applied 1b8a7d4282c0 ("spi: stm32-qspi:
Fix compilation warning in ARM64") after today's linux-next was
cut.

I suspect Patrice's patch now causes a warning on all architectures
on which size_t is defined as 'unsigned int'.

Hi Mark, Arnd

Regarding this issue, how do you prefer to proceed ?

Applied to

Thanks!

[1/1] spi: stm32-qspi: fix debug format string
      commit: 14ef64ebdc2a4564893022780907747567452f6c

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark
