GSoC Linux UIO driver for PRU

[Nils Hölscher]

Hi,

I am currently porting the pruss driver functions, that I want to add in:
rtems_filesystem_file_handlers_r pruss_irq_handler.
But when I add  my functions like this:
  .open_h = ti_pruss_irq_open
I receive the following compiler warnings:
../../pruss.c:156:13: warning: initialization from incompatible pointer
type [-Wincompatible-pointer-types]
   .open_h = ti_pruss_irq_open,
             ^~~~~~~~~~~~~~~~~
../../pruss.c:156:13: note: (near initialization for
'pruss_irq_handler.open_h')
../../pruss.c:158:13: warning: initialization from incompatible pointer
type [-Wincompatible-pointer-types]
   .read_h = ti_pruss_irq_read,

Can anyone help please?

Best,
