Subject: [PATCH] drivers: staging: vme: Fixed code style issues
From: Egor Uleyskiy <egor.ulieiskii@...il.com>
* Fixed indention
* Deleted extra empty lines
* Constructions that looks like
card = kzalloc(sizeof(struct pio2_card), GFP_KERNEL);
are changed to
card = kzalloc(sizeof(*card), GFP_KERNEL);
