Commit 40f7090bb1b4 ("Input: elan_i2c_smbus - fix corrupted stack") fixed most of the functions using i2c_smbus_read_block_data() to allocate a buffer with the maximum block size. However three functions were left unchanged: * In elan_smbus_initialize(), increase the buffer size in the same way. * In elan_smbus_calibrate_result(), the buffer is provided by the caller (calibrate_store()), so introduce a bounce buffer. Also name the result buffer size. * In elan_smbus_get_report(), the buffer is provided by the caller but happens to be the right length. Add a compile-time assertion to ensure this remains the case.
