2017-02-11crypto: atmel - fix 64-bit build warningsArnd Bergmann1-7/+7
When we enable COMPILE_TEST building for the Atmel sha and tdes implementations, we run into a couple of warnings about incorrect format strings, e.g. In file included from include/linux/platform_device.h:14:0, from drivers/crypto/atmel-sha.c:24: drivers/crypto/atmel-sha.c: In function 'atmel_sha_xmit_cpu': drivers/crypto/atmel-sha.c:571:19: error: format '%d' expects argument of type 'int', but argument 6 has type 'size_t {aka long unsigned int}' [-Werror=format=] In file included from include/linux/printk.h:6:0, from include/linux/kernel.h:13, from drivers/crypto/atmel-tdes.c:17: drivers/crypto/atmel-tdes.c: In function 'atmel_tdes_crypt_dma_stop': include/linux/kern_levels.h:4:18: error: format '%u' expects argument of type 'unsigned int', but argument 2 has type 'size_t {aka long unsigned int}' [-Werror=format=] These are all fixed by using the "%z" modifier for size_t data. There are also a few uses of min()/max() with incompatible types: drivers/crypto/atmel-tdes.c: In function 'atmel_tdes_crypt_start': drivers/crypto/atmel-tdes.c:528:181: error: comparison of distinct pointer types lacks a cast [-Werror] Where possible, we should use consistent types here, otherwise we can use min_t()/max_t() to get well-defined behavior without a warning.

2016-03-11crypto: atmel - fix checks of error code returned by devm_ioremap_resource()Vladimir Zapolskiy1-2/+2
The change fixes potential oops while accessing iomem on invalid address, if devm_ioremap_resource() fails due to some reason. The devm_ioremap_resource() function returns ERR_PTR() and never returns NULL, which makes useless a following check for NULL.

2015-04-08crypto: atmel-tdes - initialize spinlock in probeLeilei Zhao1-0/+1
Kernel will report "BUG: spinlock lockup suspected on CPU#0" when CONFIG_DEBUG_SPINLOCK is enabled in kernel config and the spinlock is used at the first time. It's caused by uninitialized spinlock, so just initialize it in probe.

2014-08-01crypto: atmel-tdes - Switch to managed version of kzallocPramod Gurav1-7/+1
This patch switches data allocation from kzalloc to devm_kzalloc. It also removes some kfree() on data that was earlier allocated using devm_kzalloc() from probe as well as remove funtions.

2013-01-04Drivers: crypto: remove __dev* attributes.Greg Kroah-Hartman1-3/+3
CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

2012-08-01crypto: drivers - remove cra_list initializationJussi Kivilinna1-1/+0
Initialization of cra_list is currently mixed, most ciphers initialize this field and most shashes do not. Initialization however is not needed at all since cra_list is initialized/overwritten in __crypto_register_alg() with list_add(). Therefore perform cleanup to remove all unneeded initializations of this field in 'crypto/drivers/'.
