Subject: [PATCH v2] Remove unnecessary variable assignment in agp_generic_create_gatt_table()
Remove unnecessary variable assignments 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]
Signed-off-by: Gautam Menghani <gautammenghani201@...il.com>

changes in v2:
1. Initialize the variables where they are declared.
