[PATCH 0/5] STM32: Fix build warnings about export.h

[Antonio Borneo]

This series fixes, for the SoC's STM32, the new warnings that
appear from v6.16-rc1 about mismatch between the include of
linux/export.h and the use of EXPORT_SYMBOL().

Antonio Borneo (5):
  bus: stm32_firewall: Fix build warnings about export.h
  iio: adc: stm32-dfsdm: Fix build warnings about export.h
  iio: trigger: stm32-timer: Fix build warnings about export.h
  iio: trigger: stm32-lptimer: Fix build warnings about export.h
  mfd: stm32-timers: Fix build warnings about export.h

[Antonio Borneo]

After commit a934a57a42f6 ("scripts/misc-check: check missing #include
<linux/export.h> when W=1") and commit 7d95680d64ac ("scripts/misc-check:
check unnecessary #include <linux/export.h> when W=1") we get the build
warning with W=1:
