      staging: iio: cdc: use devm_iio_device_register instead iio_device_register · 252fb58c
      Ioana Ciornei authored 
      Replace iio_device_register with resource managed devm_iio_device_register in order
to ease the error path. Also delete de remove function since there is no need after
this change.

      staging: wlan-ng: prism2sta: replace memcmp with ether_addr_equal · a305cf31
      Maciek Borzecki authored 
      Replace memcmp() with ether_addr_equal(). In every location where the
replacement was done, the addresses accessed are
__aligned(2). Structures accessed either stack or heap allocated, no
direct memory casts to possibly unaligned structs are used.

Involved structures:

typedef struct hfa384x_authenticateStation_data {
	u8 address[ETH_ALEN];   /* 0 offset */
	...
} __packed hfa384x_authenticateStation_data_t;

struct prism2sta_authlist {
	unsigned int cnt;
	u8 addr[WLAN_AUTH_MAX][ETH_ALEN]; /* 4 bytes offset,
					     addresses start
					     at u16 boundary */
	u8 assoc[WLAN_AUTH_MAX];
};

struct prism2sta_accesslist {
	unsigned int modify;
	unsigned int cnt;
	u8 addr[WLAN_ACCESS_MAX][ETH_ALEN]; /* 8 bytes offset,
					       multiple of u16 */
	...
	u8 addr1[WLAN_ACCESS_MAX][ETH_ALEN]; /* starts at u32 boundary,
						struct not packed */
};

typedef struct hfa384x_AssocStatus {
	u16 assocstatus;
	u8 sta_addr[ETH_ALEN];    /* 2 bytes offset,
				     struct is packed */
	u8 old_ap_addr[ETH_ALEN]; /* 8 bytes offset */
	...
} __packed hfa384x_AssocStatus_t;

The patch resolves the following checkpatch warnings:

  WARNING: Prefer ether_addr_equal() or ether_addr_equal_unaligned()
           over memcmp()
