Merge branch 'fixes-for-3.6' of git://gitorious.org/linux-can/linux-can
Marc Kleine-Budde says:
====================
here are two fixes for the v3.6 release cycle. Alexey Khoroshilov submitted a
fix for a memory leak in the softing driver (in softing_load_fw()) in case a
krealloc() fails. Sven Schmitt fixed the misuse of the IRQF_SHARED flag in the
irq resouce of the sja1000 platform driver, now the correct flag is used. There
are no mainline users of this feature which need to be converted.
====================
