[ Upstream commit e864a77f51d0d8113b49cf7d030bc9dc911c8176 ] If the data we get from EFI is not even long enough for the package struct we expect then ignore it entirely.

iwlwifi: pnvm: don't kmemdup() more than we have

[ Upstream commit 0f892441d8c353144e3669b7991fa5fe0bd353e9 ] We shouldn't kmemdup() more data than we have, that might cause the code to crash. Fix that by updating the length before the kmemdup.

[ Upstream commit 2f629a7772e2a7bdaff25178917a40073f79702c ] If resume fails for some reason, we need to set the PM state back to normal so we're able to send commands during firmware reset, rather than failing all of them because we're in D3.

iwlwifi: mvm: disable RX-diversity in powersave

[ Upstream commit e5322b9ab5f63536c41301150b7ce64605ce52cc ] Just like we have default SMPS mode as dynamic in powersave, we should not enable RX-diversity in powersave, to reduce power consumption when connected to a non-MIMO AP.

iwlwifi: pnvm: Fix a memory leak in 'iwl_pnvm_get_from_fs()'

2021-09-22T10:39:32Z

[ Upstream commit 45010c080e6e7434fcae73212b0087a03590049f ] A firmware is requested but never released in this function. This leads to a memory leak in the normal execution path. Add the missing 'release_firmware()' call. Also introduce a temp variable (new_len) in order to keep the value of 'pnvm->size' after the firmware has been released.
