From 915d9b71422126076f1971f1a44561ae76890060 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Thu, 28 Jun 2018 12:23:10 +0300 Subject: [PATCH] scsi: qedi: tidy up a size calculation The id_tbl->table pointer points to unsigned long so static checkers complain that instead of 4 we should be allocating sizeof(long) bytes. We're trying to allocate enough bits for the bitmap. The size variable is always 1024. (1024 / 32 * 4) is the same as (1024 / 64 * 8) so this doesn't change runtime, but this is the more idiomatic way to do it and makes the static checker happy.
