Subject: [PATCH] mtd: rawnand: qcom: handle ret from parse with codeword_fixup
|
|
|
|
With use_codeword_fixup enabled, any return from
|
|
mtd_device_parse_register gets overwritten. Aside from the clear bug, this
|
|
is also problematic as a parser can EPROBE_DEFER and because this is not
|
|
correctly handled, the nand is never rescanned later in the bootup
|
|
process.
|
|
|
|
An example of this problem is when smem requires additional time to be
|
|
probed and nandc use qcomsmempart as parser. Parser will return
|
|
EPROBE_DEFER but in the current code this ret gets overwritten by
|
|
qcom_nand_host_parse_boot_partitions and qcom_nand_host_init_and_register
|
|
return 0.
|
|
|
|
Correctly handle the return code from mtd_device_parse_register so that
|
|
any error from this function is not ignored.
|
|
