| Subject: Net, libertas: Resolve memory leak in if_spi_host_to_card() |
| |
| From: Jesper Juhl <jj@chaosbits.net> |
| |
| commit fe09b32a4361bea44169b2063e8c867cabb6a8ba upstream. |
| |
| If we hit the default case in the switch in if_spi_host_to_card() we'll leak |
| the memory we allocated for 'packet'. This patch resolves the leak by freeing |
| the allocated memory in that case. |
