The goal of the dw_pcie_ep_init_complete() API is to initialize the DWC

For DWC glue drivers supporting PERST# (currently Qcom and Tegra194), some

dw_pcie_ep_exit() API is undoing what the dw_pcie_ep_init() API has done

deinit() callback was solely introduced for the pcie-rcar-gen4 driver where
it is used to do platform specific resource deallocation. And this callback
is called right at the end of the dw_pcie_ep_exit() API. So it doesn't

All of the APIs are missing the Kernel-doc comments. Hence, add them.

Hello,
This series is the continuation of previous work by Vidya Sagar [1] to fix the

clang warns about what it interprets as a truncated snprintf:

From: Arnd Bergmann
With randconfig build testing, I found only eight files that produce
warnings with clang when -Wformat-truncation is enabled. This means
we can just turn it on by default rather than only enabling it for
"make W=1".
Unfortunately, gcc produces a lot more warnings when the opt

IMHO you should split the changes to replace ARCH_HAVE_EXTRA_ELF_NOTES
with CONFIG_ARCH_HAVE_EXTRA_ELF_NOTES into a lead-up patch.

Thanks for the input and i will take care in next version.

Otherwise looks reasonable, though I see Dave has feedback to address
