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. Signed-off-by: Colin Ian King <colin.king@canonical.com> Signed-off-by: Mark Brown <broonie@kernel.org>
