Subject: [PATCH] thunderbolt: Use const qualifier for `ring_interrupt_index`
Git-commit: 1716efdb07938bd6510e1127d02012799112c433
Patch-mainline: v6.3-rc4
References: git-fixes
`ring_interrupt_index` doesn't change the data for `ring` so mark it as
const. This is needed by the following patch that disables interrupt
auto clear for rings.
