Subject: [PATCH] spi: spi-qpic-snand: avoid memleak in
|
|
qcom_spi_ecc_init_ctx_pipelined()
|
|
|
|
When the allocation of the OOB buffer fails, the
|
|
qcom_spi_ecc_init_ctx_pipelined() function returns without freeing
|
|
the memory allocated for 'ecc_cfg' thus it can cause a memory leak.
|
|
|
|
Call kfree() to free 'ecc_cfg' before returning from the function
|
|
to avoid that.
|
|
|
