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.
