Tong Zhang d82d5303c4 net: macb: fix use after free on rmmod
plat_dev->dev->platform_data is released by platform_device_unregister(),
use of pclk and hclk is a use-after-free. Since device unregister won't
need a clk device we adjust the function call sequence to fix this issue.

[   31.261225] BUG: KASAN: use-after-free in macb_remove+0x77/0xc6 [macb_pci]
[   31.275563] Freed by task 306:
[   30.276782]  platform_device_release+0x25/0x80

Alexandre Belloni 20c168be68 net: macb: move pdata to private header
struct macb_platform_data is only used by macb_pci to register the platform
device, move its definition to cadence/macb.h and remove platform_data/macb.h

Jesse Brandeburg f410f157f4 drivers/net/ethernet: add some basic kdoc tags
A couple of drivers had a "generic documentation" section that
would trigger a "can't understand" message from W=1 compiles.

Fix by using correct DOC: tags in the generic sections.

Fixed Warnings:

drivers/net/ethernet/cadence/macb_pci.c:3: warning: missing initial short description on line:
 * Cadence GEM PCI wrapper.

Alexander A. Klimov 5d75c04306 Replace HTTP links with HTTPS ones: ATMEL MACB ETHERNET DRIVER
Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.

Deterministic algorithm:
For each file:
  If not .svg:
    For each line:
      If doesn't contain `\bxmlns\b`:
        For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
	  If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`:
            If both the HTTP and HTTPS versions
            return 200 OK and serve the same content:
              Replace HTTP with HTTPS.

Arvind Yadav c744cf5b9d net: cadence: macb: constify pci_device_id.
pci_device_id are not supposed to change at runtime. All functions
working with pci_device_id provided by <linux/pci.h> work with
const pci_device_id. So mark the non-const structs as const.

File size before:
   text	   data	    bss	    dec	    hex	filename
    791	    336	      0	   1127	    467	net/ethernet/cadence/macb_pci.o

File size After adding 'const':
