| Subject: wifi: rtw89: Disable deep power saving for USB/SDIO |
| |
| From: Bitterblue Smith <rtl8821cerfe2@gmail.com> |
| |
| [ Upstream commit a3b871a0f7c083c2a632a31da8bc3de554ae8550 ] |
| |
| Disable deep power saving for USB and SDIO because rtw89_mac_send_rpwm() |
| is called in atomic context and accessing hardware registers results in |
| "scheduling while atomic" errors. |
