From dfb85ba1140ab649f6f0bf3e502ac37c0f69dbcb Mon Sep 17 00:00:00 2001 From: Colin Ian King Date: Tue, 7 Apr 2015 23:06:46 +0100 Subject: regulator: max8660: fix assignment of pdata to data that becomes dead pdata is assigned to &pdata_of, however, pdata_of becomes dead (when it goes out of scope) so pdata effectively becomes a dead pointer to the out of scope object. This is detected by static analysis: [drivers/regulator/max8660.c:411]: (error) Dead pointer usage. Pointer 'pdata' is dead if it has been assigned '&pdata_of' at line 404. Move declaration of pdata_of so it is always in scope.
