Subject: [PATCH] drivers/char/agp: Remove unnecessary variable assignment in agp_generic_create_gatt_table()
Date:   Thu, 16 Jun 2022 23:49:39 +0530

Remove unnecessary variable assignment in the function
agp_generic_create_gatt_table(). This fixes the clang scan warnings:

warning: Value stored to 'page_order' is never read [deadcode.DeadStores]
        page_order = num_entries = 0;

warning: Although the value stored to 'num_entries' is used in the
enclosing expression, the value is never actually read from 'num_entries'
[deadcode.DeadStores]
