Subject: [PATCH] thunderbolt: Replace usage of found with dedicated list
iterator variable
Git-commit: 03941ed91c7231e4973fb50de6c349974405df4e
References: jsc#PED-531 jsc#PED-1211
Patch-mainline: v5.19-rc1
To move the list iterator variable into the list_for_each_entry_*()
macro in the future it should be avoided to use the list iterator
variable after the loop body.
To *never* use the list iterator variable after the loop it was
concluded to use a separate iterator variable instead of a
found boolean [1].
This removes the need to use a found variable and simply checking if
the variable was set, can determine if the break/goto was hit.
