[ Upstream commit 44ef3a03252844a8753479b0cea7f29e4a804bdc ] In i2400m_barker_db_init(), 'options_orig' is allocated through kstrdup() to hold the original command line options. Then, the options are parsed. However, if an error occurs during the parsing process, 'options_orig' is not deallocated, leading to a memory leak bug. To fix this issue, free 'options_orig' before returning the error. Signed-off-by: Wenwen Wang <wenwen@xxxxxxxxxx> Signed-off-by: David S.
