[ Upstream commit 1f447e51c0b9e8beeec0917ea5f51930f55e17c9 ]
Currently we have structrues comp (which is empty) and comp_info being used to register and deregister the component. This mismatch in naming occurred from a previous commit that renamed aim_info to comp. Fix this to use consistent component naming in line with most/net, most/sound etc.
This fixes the message two issues, one with a null empty name when loading the module:
[ 1485.269515] most_core: registered new core component (null)
and an Oops when removing the module:
[ 1485.277971] BUG: unable to handle kernel NULL pointer dereference at 0000000000000008 [ 1485.278648] PGD 0 P4D 0 [ 1485.279253] Oops: 0002 [#2] SMP PTI [ 1485.279847] CPU: 1 PID: 32629 Comm: modprobe Tainted: P D WC OE 4.18.0-8-generic #9 [ 1485.280442] Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 0.0.0 02/06/2015 [ 1485.281040] RIP: 0010:most_deregister_component+0x3c/0x70 [most_core] .. etc
