[PATCH 1/1 v2] xen: xenbus: set error code on failure

Variable err is initialized with 0. As a result, the return value may be 0 even if get_zeroed_page() fails to allocate memory. This patch fixes the bug, initializing err with "-ENOMEM". v1 is reviewed by: Juergen Gross Signed-off-by: Pan Bian --- drivers/xen/xenbus/xenbus_probe.c | 2 +- 1 fi

[PATCH 1/1 v2] xen: set error code on failures

Variable rc is reset in the loop, and its value will be non-negative during the second and after repeat of the loop. If it fails to allocate memory then, it may return a non-negative integer, which indicates no error. This patch fixes the bug, assigning "-ENOMEM" to rc when kzalloc() or alloc_page(
