[PATCH] remoteproc: st: Fix indexing of memory-regions
Posted by Bjorn Andersson 5 days, 3 hours ago
The recent transition to use of_reserved_mem_region_to_resource()
changes the while loop to a for loop, but the increment of the "index"
variable was left behind at the end of the loop, as highlighted by the
following error/warning:

  error: variable 'index' is incremented both in the loop header and in the loop body [-Werror,-Wfor-loop-analysis]

Drop the extra increment to avoid skipping over every other
memory-region in the loop.

Fixes: 67a7bc7f0358 ("remoteproc: Use of_reserved_mem_region_* functions for "memory-region"")
