    gdrom: fix a memory leak bug · 49e14c1d

    In probe_gdrom(), the buffer pointed by 'gd.cd_info' is allocated through
    kzalloc() and is used to hold the information of the gdrom device. To
    register and unregister the device, the pointer 'gd.cd_info' is passed to
    the functions register_cdrom() and unregister_cdrom(), respectively.
    However, this buffer is not freed after it is used, which can cause a
    memory leak bug.
    
    This patch simply frees the buffer 'gd.cd_info' in exit_gdrom() to fix the
    above issue.
