[PATCH] ARM: pxa: remove use of symbol_get()

From: Arnd Bergmann
Date: Mon Jul 31 2023 - 16:35:39 EST


From: Arnd Bergmann <arnd@xxxxxxxx>

The spitz board file uses the obscure symbol_get() function
to optionally call a function from sharpsl_pm.c if that is
built. However, the two files are always built together
these days, and have been for a long time, so this can
be changed to a normal function call.

Signed-off-by: Arnd Bergmann <arnd@xxxxxxxx>

This should get merged along with Christoph's other
patches for updating the symbol_get() references to
use EXPORT_SYMBOL_GPL().
