drm/amd/display: Fix potential memory leak in DMUB hw_init

2021-06-18T08:02:51Z

[ Upstream commit c5699e2d863f58221044efdc3fa712dd32d55cde ] [Why] On resume we perform DMUB hw_init which allocates memory: dm_resume->dm_dmub_hw_init->dc_dmub_srv_create->kzalloc That results in memory leak in suspend/resume scenarios. [How] Allocate memory for the DC wrapper to DMUB only if it was not allocated before. No need to reallocate it on suspend/resume.

net: ipconfig: Don't override command-line hostnames or domains

2021-06-18T08:02:51Z

[ Upstream commit b508d5fb69c2211a1b860fc058aafbefc3b3c3cd ] If the user specifies a hostname or domain name as part of the ip= command-line option, preserve it and don't overwrite it with one supplied by DHCP/BOOTP. For instance, ip=::::myhostname::dhcp will use "myhostname" rather than ignoring and overwriting it. Fix the comment on ic_bootp_string that suggests it only copies a string "if not already set"; it doesn't have any such logic. Signed-off-by: Josh Triplett Signed-off-by: David S.
