Wenwen Wang 711b2e7fc0 gdrom: fix a memory leak bug ... [ Upstream commit 093c48213e ] 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.
