[PATCH v2 1/9] qla2xxx: Check the size of struct fcp_hdr at compile time

[Bart Van Assche]

Since struct fcp_hdr is used to exchange data with the firmware, check its
size at compile time.

[PATCH v2 2/9] qla2xxx: Remove the __packed annotation from struct fcp_hdr and fcp_hdr_le

[Bart Van Assche]

Remove the __packed annotation from struct fcp_hdr* because that annotation

[PATCH v2 3/9] qla2xxx: Make qla82xx_flash_wait_write_finish() easier to read

[Bart Van Assche]

Return early instead of having a single return statement at the end of this
function. This patch fixes the following sparse warning:

qla_nx.c:1018: qla82xx_flash_wait_write_finish() error: uninitialized symbol 'val'.

[PATCH v2 4/9] qla2xxx: Initialize 'n' before using it

[Bart Van Assche]

The following code:
	qla82xx_rom_fast_read(ha, 0, &n)
only initializes 'n' if it succeeds. Since 'n' may be reported in a debug
message even if no ROM reads succeeded, initialize 'n' to zero.

This patch fixes the following sparse warning:

qla_nx.c:1218: qla82xx_pinit_from_rom() error: uninitialized symbol 'n'.

[PATCH v2 6/9] qla2xxx: Make __qla2x00_alloc_iocbs() initialize 32 bits of request_t.handle

[Bart Van Assche]

The request_t 'handle' member is 32-bits wide, hence use wrt_reg_dword().
Change the cast in the wrt_reg_byte() call to make it clear that a
regular pointer is casted to an __iomem pointer.

Note: 'pkt' points to I/O memory for the qlafx00 adapter family and to
coherent memory for all other adapter families.

This patch fixes the following Coverity complaint:

CID 358864 (#1 of 1): Reliance on integer endianness (INCOMPATIBLE_CAST)
incompatible_cast: Pointer &pkt->handle points to an object whose effective
type is unsigned int (32 bits, unsigned) but is dereferenced as a narrower
unsigned short (16 bits, unsigned). This may lead to unexpected results
depending on machine endianness.
