Reapply, with minor tweaks, r338025, from the original commit:

2018-09-26T17:12:14Z

Remove unused and easy to misuse PNP macro parameter Inspired by r338025, just remove the element size parameter to the MODULE_PNP_INFO macro entirely. The 'table' parameter is now required to have correct pointer (or array) type. Since all invocations of the macro already had this property and the emitted PNP data continues to include the element size, there is no functional change. Mostly done with the coccinelle 'spatch' tool: $ cat modpnpsize0.cocci @normaltables@ identifier b,c; expression a,d,e; declarer MODULE_PNP_INFO; @@ MODULE_PNP_INFO(a,b,c,d, -sizeof(d[0]), e); @singletons@ identifier b,c,d; expression a; declarer MODULE_PNP_INFO; @@ MODULE_PNP_INFO(a,b,c,&d, -sizeof(d), 1); $ rg -l MODULE_PNP_INFO -- sys | \ xargs spatch --in-place --sp-file modpnpsize0.cocci (Note that coccinelle invokes diff(1) via a PATH search and expects diff to tolerate the -B flag, which BSD diff does not. So I had to link gdiff into PATH as diff to use spatch.) Tinderbox'd (-DMAKE_JUST_KERNELS). Approved by: re (glen)

Back out r338035 until Warner is finished churning GSoC PNP patches

I was not aware Warner was making or planning to make forward progress in this area and have since been informed of that. It's easy to apply/reapply when churn dies down.

puc(4): Add provisional support for Exar XR17V352

2018-06-06T16:47:33Z

Reportedly, this is sufficient for 4800bps use, but maybe not any better. PR: 228781 Submitted by: peo AT nethead.se

Add PNP info to the PCI attahement of the puc driver.

Adjust sys/conf/files and sys/modules/puc/Makefile to omit pucdata.c now tht it's included by puc_pci.c. Submitted by: Lakhan Shiva Kamireddy (with build fixes by me) Pull Request: https://github.com/freebsd/freebsd/pull/136

sys/dev: further adoption of SPDX licensing ID tags.

2017-11-27T14:52:40Z

Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts.

Fix device delete child function.

2016-10-17T10:20:38Z

When detaching device trees parent devices must be detached prior to detaching its children. This is because parent devices can have pointers to the child devices in their softcs which are not invalidated by device_delete_child(). This can cause use after free issues and panic(). Device drivers implementing trees, must ensure its detach function detaches or deletes all its children before returning. While at it remove now redundant device_detach() calls before device_delete_child() and device_delete_children(), mostly in the USB controller drivers.

Convert rman to use rman_res_t instead of u_long

2016-01-27T02:23:54Z

Summary: Migrate to using the semi-opaque type rman_res_t to specify rman resources. For now, this is still compatible with u_long. This is step one in migrating rman to use uintmax_t for resources instead of u_long. Going forward, this could feasibly be used to specify architecture-specific definitions of resource ranges, rather than baking a specific integer type into the API. This change has been broken out to facilitate MFC'ing drivers back to 10 without breaking ABI.
