X-Git-Tag: microblaze-v5.11~95^2~13 X-Git-Url: http://git.monstr.eu/?a=commitdiff_plain;h=73c5265913b4b11a56d119396f745a57c7c272b7;p=linux-2.6-microblaze.git RDMA/bnxt_re: Fix sizeof mismatch for allocation of pbl_tbl. An incorrect sizeof is being used, u64 * is not correct, it should be just u64 for a table of umem_pgs number of u64 items in the pbl_tbl. Use the idiom sizeof(*pbl_tbl) to get the object type without the need to explicitly use u64.
