Moreover, pn544.c is outdated and does not seem to + work properly with the latest Android stacks. + Having 2 drivers for the same hardware is confusing and as such we + should only keep the one following the kernel NFC APIs. +Who: Samuel Ortiz <sameo@linux.intel.com> + +---------------------------- + What: setitimer accepts user NULL pointer (value) When: 3.6 Why: setitimer is not returning -EFAULT if user pointer is NULL.
