d6b07f39eb wimax: i2400: Fix memory leak in i2400m_op_rfkill_sw_toggle
commit 6f3ef5c25cc762687a7341c18cbea5af54461407 upstream.

In the implementation of i2400m_op_rfkill_sw_toggle() the allocated
buffer for cmd should be released before returning. The
documentation for i2400m_msg_to_dev() says when it returns the buffer
can be reused. Meaning cmd should be released in either case. Move
kfree(cmd) before return to be reached by all execution paths.

3b71ed7429 wimax/i2400m: fix a memory leak bug
[ 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.
