From: Jiapeng Chong <redacted>

The value stored to ptr in the calculations this patch removes is not
used, so the calculation and the assignment can be removed.

Cleans up the following clang-analyzer warning:

drivers/net/can/softing/softing_main.c:279:3: warning: Value stored to
'ptr' is never read [clang-analyzer-deadcode.DeadStores].

drivers/net/can/softing/softing_main.c:242:3: warning: Value stored to
'ptr' is never read [clang-analyzer-deadcode.DeadStores].
