From: Yanir Lubetkin Date: Sat, 21 Mar 2015 00:41:53 +0000 (-0700) Subject: e1000e: NVM write protect access removed from SPT HW X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=152c0a976c71386c67c89969acc427dc5cf802b8;p=linux-beck.git e1000e: NVM write protect access removed from SPT HW The call to e1000e_write_protect_nvm_ich8lan() is no longer supported by HW. Access to these registers causes a system freeze in A step hardware and is ignored in B step hardware. This function must not be called in hardware newer than LPT.
