2013-06-06pch_phub: fix error return code in pch_phub_probe()Wei Yongjun1-19/+17
Error code had been assigned to retval in some error handling case but never use it, 0 is always returned in those case, this patch fix them to return a negative error code. Signed-off-by: Wei Yongjun <yongjun_wei@trendmicro.com.cn> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2013-06-06misc: replace strict_strtoul() with kstrtoul()Jingoo Han14-83/+154
The usage of strict_strtoul() is not preferred, because strict_strtoul() is obsolete. Thus, kstrtoul() should be used. Signed-off-by: Jingoo Han <jg1.han@samsung.com> Reviewed-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2013-06-05net: core: move mac_pton() to lib/net_utils.cAndy Shevchenko1-0/+1
Since we have at least one user of this function outside of CONFIG_NET scope, we have to provide this function independently. The proposed solution is to move it under lib/net_utils.c with corresponding configuration variable and select wherever it is needed.

2013-04-30misc: generic on-chip SRAM allocation driverPhilipp Zabel3-0/+131
This driver requests and remaps a memory region as configured in the device tree. It serves memory from this region via the genalloc API. It optionally enables the SRAM clock. Other drivers can retrieve the genalloc pool from a phandle pointing to this drivers' device node in the device tree. The allocation granularity is hard-coded to 32 bytes for now, to make the SRAM driver useful for the 6502 remoteproc driver. There is overhead for bigger SRAMs, where only a much coarser allocation granularity is needed: At 32 bytes minimum allocation size, a 256 KiB SRAM needs a 1 KiB bitmap to track allocations.

This driver was merged in 2.6.38 but never actually compiled because it depends on the <mach/pcie.h> header that has not made it into the kernel.
