There are multiple (16) modules which use a module_init() function
with the name 'mod_init' and a module_exit() function with the name
'mod_exit'. This can lead to confusion or ambiguity when reading
crashes/oops/bugs etc. and when reading an initcall_debug log.

Example 1: (System.map file)

ffffffff83446d10 t mod_init
ffffffff83446d18 t mod_init
ffffffff83446d20 t mod_init
...
ffffffff83454665 t mod_init
ffffffff834548a4 t mod_init
ffffffff83454a53 t mod_init
...
ffffffff8345bd42 t mod_init
...
ffffffff8345c916 t mod_init
ffffffff8345c92a t mod_init
ffffffff8345c93e t mod_init
ffffffff8345c952 t mod_init
ffffffff8345c966 t mod_init
...
ffffffff834672c9 t mod_init

Example 2: (boot log when using 'initcall_debug')

[    0.252157] initcall mod_init+0x0/0x8 returned 0 after 0 usecs
[    0.252180] initcall mod_init+0x0/0x8 returned 0 after 0 usecs
[    0.252202] initcall mod_init+0x0/0x8 returned 0 after 0 usecs
...
[    0.892907] initcall mod_init+0x0/0x23f returned -19 after 104 usecs
[    0.913788] initcall mod_init+0x0/0x1af returned -19 after 9 usecs
[    0.934353] initcall mod_init+0x0/0x49 returned -19 after 0 usecs
...
[    1.454870] initcall mod_init+0x0/0x66 returned 0 after 72 usecs

[    1.455536] initcall mod_init+0x0/0x14 returned 0 after 0 usecs
[    1.455541] initcall mod_init+0x0/0x14 returned 0 after 0 usecs
[    1.455545] initcall mod_init+0x0/0x52 returned 0 after 0 usecs
...
[    1.588162] initcall mod_init+0x0/0xef returned 0 after 45 usecs
