Subject: csr1212: check results of keyval reads
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=5303a986c33ae6c75d5ffb57d06ccf9246a8725a;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git

csr1212: check results of keyval reads

csr1212_parse_csr() did not properly check return values when reading
keyvals.  Fix this by using _csr1212_read_keyval() instead of
csr1212_get_keyval() and checking the return code.
