[PATCH] module: procfs: fix signed integer overflow in module_total_size()

From: Naveen Kumar Chaudhary

Date: Wed Jun 03 2026 - 12:57:28 EST


module_total_size() accumulates unsigned section sizes into a signed int
before returning as unsigned int. If the total exceeds INT_MAX, this is
signed integer overflow.

Change the accumulator to unsigned int to match the return type.
