Subject: [merged] hpet-remove-useless-check-if-fixmem32-is-null.patch removed from -mm tree To: tomas.winkler@xxxxxxxxx,clemens@xxxxxxxxxx,msw@xxxxxxxxxx,prarit@xxxxxxxxxx,rdunlap@xxxxxxxxxxxxx,mm-commits@xxxxxxxxxxxxxxx From: akpm@xxxxxxxxxxxxxxxxxxxx Date: Mon, 30 Sep 2013 15:22:12 -0700 The patch titled Subject: drivers/char/hpet.c: remove useless check if fixmem32 is NULL has been removed from the -mm tree. Its filename was hpet-remove-useless-check-if-fixmem32-is-null.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Tomas Winkler <tomas.winkler@xxxxxxxxx> Subject: drivers/char/hpet.c: remove useless check if fixmem32 is NULL fixmem32 is assigned to address of res->data member so the address is always valid Actually since we are not checking for res != NULL static analyzing is complaining about referencing the pointer and consequent check for null. The code snippet looks confusing also for human eyes.
