If read_symbols() fails during second list traversal (the one dealing
with ".cold" subfunctions) it frees the symbol, but never deletes it
from the list/hash_table resulting in symbol being freed again in
elf_close(). Fix by just returning an error leaving cleanup to
elf_close().
Fixes: 13810435b9
Because find_symbol_by_name() traverses the same lists as read_symbols()
changing sym->name in place without copying it affects the result of
find_symbol_by_name() and, in case when ".cold" function precedes it's
parent in sec->symbol_list, can result in function being considered a
parent of itself
The series started with 'parent symbol search' patch, but I found another issue
in read_symbols() while testing the failure-path.

On SAMA5D2 SoC the PIOBU pins do not lose their
voltage during Backup/Self-refresh mode. This can
be useful, for example, when the voltage must remain
positive for a peripheral during Backup/Self-refresh
mode (suspend-to ram is the Linux equivalent state).

PIOBU pins do not lose their voltage during Backup/Self-refresh.
This patch adds a simple GPIO controller for them and a
maintainer for the driver.
This driver adds support for using the pins as GPIO
offering the possibility to read/set the voltage.

PCIe Gen4 controller.

It's confused that R/W some registers by csr_readl()/csr_writel(),
while others by read_paged_register()/write_paged_register().
Actually the low 3KB of 4KB PCIe configure space can be accessed
directly and high 1KB is paging area. So this patch uniformed the
register accessors

The inbound windows have different register set with outbound windows.
