There are a number of drivers that use "module_init(init)" and
"module_exit(exit)", which are anonymous names and can lead to
confusion or ambiguity when reading System.map, crashes/oops/bugs,
or an initcall_debug log.

Give each of these init and exit functions unique driver-specific
names to eliminate the anonymous names.

Example 1: (System.map)
 ffffffff832fc78c t init
 ffffffff832fc79e t init
 ffffffff832fc8f8 t init
 ffffffff832fca05 t init
 ffffffff832fcbd2 t init
 ffffffff83328f0e t init
 ffffffff8332c5b1 t init
 ffffffff8332d9eb t init
 ffffffff8332f0aa t init
 ffffffff83330e25 t init
 ffffffff833317a5 t init
 ffffffff8333dd6b t init

Example 2: (initcall_debug log)
 calling  init+0x0/0x12 @ 1
 initcall init+0x0/0x12 returned 0 after 15 usecs
 calling  init+0x0/0x60 @ 1
 initcall init+0x0/0x60 returned 0 after 2 usecs
 calling  init+0x0/0x9a @ 1
 initcall init+0x0/0x9a returned 0 after 74 usecs
 calling  init+0x0/0x73 @ 1
 initcall init+0x0/0x73 returned 0 after 6 usecs
 calling  init+0x0/0x73 @ 1
 initcall init+0x0/0x73 returned 0 after 4 usecs
 calling  init+0x0/0xf5 @ 1
 initcall init+0x0/0xf5 returned 0 after 27 usecs
 calling  init+0x0/0x7d @ 1
 initcall init+0x0/0x7d returned 0 after 11 usecs
 calling  init+0x0/0xc9 @ 1
 initcall init+0x0/0xc9 returned 0 after 19 usecs
 calling  init+0x0/0x9d @ 1
 initcall init+0x0/0x9d returned 0 after 37 usecs
 calling  init+0x0/0x63f @ 1
 initcall init+0x0/0x63f returned 0 after 411 usecs
 calling  init+0x0/0x171 @ 1
 initcall init+0x0/0x171 returned 0 after 61 usecs
 calling  init+0x0/0xef @ 1
 initcall init+0x0/0xef returned 0 after 3 usecs
