X-Git-Tag: v5.5-rc3~7^2~63^2~5 X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=325f85f37e5b35807d86185bdf2c64d2980c44ba;p=linux.git bnxt_en: Free context memory in the open path if firmware has been reset. This will trigger new context memory to be rediscovered and allocated during the re-probe process after a firmware reset. Without this, the newly reset firmware does not have valid context memory and the driver will eventually fail to allocate some resources.
