Subject: scsi: virtio-scsi: Eliminate anonymous module_init & module_exit
Git-commit: 41b8c2a31472a97349fe54c3a6b3176d9cdc31be
Patch-mainline: v5.18-rc2
References: git-fixes

Eliminate anonymous module_init() and module_exit(), which 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

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
