2013-09-02dma: replace devm_request_and_ioremap by devm_ioremap_resourceJulia Lawall1-5/+5
Use devm_ioremap_resource instead of devm_request_and_ioremap. This was done using the semantic patch scripts/coccinelle/api/devm_ioremap_resource.cocci The relevant call to platform_get_resource was manually moved down to the call to devm_ioremap_resource.

2013-09-02ACPI / LPSS: don't crash if a device has no MMIO resourcesMika Westerberg1-1/+2
Intel LPSS devices that are enumerated from ACPI have both MMIO and IRQ resources returned in their _CRS method. However, Apple Macbook Air with Haswell has LPSS devices enumerated from PCI bus instead and _CRS method returns only an interrupt number (but the device has _HID set that causes the scan handler to match it). The current ACPI / LPSS code sets pdata->dev_desc only when MMIO resource is found for the device and in case of Macbook Air it is never found. That leads to a NULL pointer dereference in register_device_clock(). Correct this by always setting the pdata->dev_desc.

2013-09-02crypto: nx - fix SHA-2 for chunks bigger than block sizeMarcelo Cerri2-2/+2
Each call to the co-processor, with exception of the last call, needs to send data that is multiple of block size. As consequence, any remaining data is kept in the internal NX context. This patch fixes a bug in the driver that causes it to save incorrect data into the context when data is bigger than the block size.

2013-09-02crypto: nx - fix GCM for zero length messagesMarcelo Cerri1-20/+112
The NX CGM implementation doesn't support zero length messages and the current implementation has two flaws: - When the input data length is zero, it ignores the associated data. - Even when both lengths are zero, it uses the Crypto API to encrypt a zeroed block using ctr(aes) and because of this it allocates a new transformation and sets the key for this new tfm. Both operations are intended to be used only in user context, while the cryptographic operations can be called in both user and softirq contexts. This patch replaces the nested Crypto API use and adds two special cases: - When input data and associated data lengths are zero: it uses NX ECB mode to emulate the encryption of a zeroed block using ctr(aes). - When input data is zero and associated data is available: it uses NX GMAC mode to calculate the associated data MAC.

2013-09-02crypto: nx - fix XCBC for zero length messagesMarcelo Cerri1-7/+77
The NX XCBC implementation doesn't support zero length messages and because of that NX is currently returning a hard-coded hash for zero length messages. However this approach is incorrect since the hash value also depends on which key is used. This patch removes the hard-coded hash and replace it with an implementation based on the RFC 3566 using ECB.

Error handling is on-its-head in this function. After invoking a function we should examine the return code and return the error value if there was one. Instead, this function checks for success and goes onto provide functionality if success was received.
